pH of 10 Common Household Liquids | Chemistry | acid or base | pH scale

[@mayckel1987]

[H+] mol/l Tap water = 3.55 e-8 Coffee = 8.51e-6 Window Cleaner = 1.14e-10 Soda = 1.34e-3 Moisturizer = 5.75e-6 Vinager = 5.37e-3 Sriracha = 1.17e-4 Shampoo = 7.94 e-7 Milk = 2.63 e-7 Lemons = 3.80 e-3

i am grade 7 and i study acid and base so i do not know h+ concentration

[@estherkim1582]

ur a beautiful soul

[@castillo2k305]

this helped me for my mid term thank you so much

[@Socratica]

That makes us so happy to hear! Thank you for letting us know!! 💜🦉

[@pinghc]

Thanks for this great demonstration, it was helpful. Lemon and coffee showed similar acidic nature, not all acids have same outcome to our body, please share a video on which acids are good to consume and which are not. Waiting for your response.

[@insightedu3278]

Soda Pop was much more acid than I was expecting! Great video!

[@thomasgronek6469]

Not only does the phosphoric acid play a BIG part, carbonic acid is also involved (not too much, I think a saturated solution yield a pH of about 5)

[@alexandrupostole7234]

The H+ concentration is the the number in the logarithm like this if im not mistaking: n=-log(10^-n) e.g. Soda Pop has the pH= 2,87 2,87=-log(10^-2,87) , so the H+ concentration is 10^-2,87

[@drumetul_dacic]

That is correct. In general: H⁺ = 10^(-pH).

THIS B***H HAD ME ROLLINGGGGGG - "We can grow lemons, YEAR ROUND here in Southern California... DONT come here..."

[@edir0z]

Good Video!! Very cool stuff. Every household has to get one of those

[@Socratica]

I bet the whole family would learn a lot having one of these pH meters! Thanks for watching! :)

[@MasayoMusic]

Great video. You deserve more views.

[@Socratica]

You are so kind! Hopefully our audience will find us! If you could share with your friends (Twitter/Reddit, etc.) that would be a huge help. Thanks so much for watching and for your kind comment! :)

[@alexandrupostole7234]

Good job. Thanks for sharing this.

[@thomasgronek6469]

Great video, Thank you. You are the best, I haven't seen a video this good for a long time! pH=-log[H+], (I will put it in English: the negative log of the hydrogen ion concentration). Did I answer your question? Or does one need to use something like the Henderson/Hasselbach equation? [inverse log or negative log]?

[@BensLab]

nice idea for a video..science starts at home!

[@Socratica]

Thanks Ben! Amazing what you can find out playing with a few tools at home! :)

[@11kiere]

hi ! thanks for the video it was really helpful ! got a good grade on my science experiment.....

[@ejecutor35]

this is fun, everything close to ph 7 is eatable? how can I get that meter?

[@ModeZt]

ejecutor35 do you drink shampoo? it is quite close to pH 7..

[@edir0z]

ejecutor35 you can find the link for the Amazon listing in the videos description

[@cristinabalan4037]

Lemon, vinegar, tomatoes, onions, garlic, strawberries... are not edible?

[@Socratica]

I wouldn't eat something just because it was pH 7, no! :) Probably lots of toxic things are close to pH 7. Rozway offered our viewers a discount on the pH meter! Here's a link to Amazon and a discount code (good until the end of Feb 2017): Socratica sends a big thank you to Rozway for sending us their digital pH meter to use in this video! For a limited time, Rozway is offering 15% off Amazon's list price on their pH meter to Socratica subscribers. Use this link to take advantage of this offer!

[@elbryan9]

Just a suggestion but if someone has, "a big gap" in their knowledge of chemistry, it might be a good idea to define what an H+ ion is. But otherwise, very cool video!

[@Socratica]

hehehe...can't teach them all of chemistry in one video! Maybe after this video, they can watch our more hard-hitting pH video with calculations - that one shows water auto-ionizing: bit.ly/1MjWY19 Thanks for watching! :)

[@UHFStation1]

How does one calibrate one of those ph meters? I don't like using random chemicals if I plan to use the meter with foods. Anyway to force something to a very particular ph? Distill the hell out of water? Also are bases slippery because it pulls fats from our fingers?

[@literallyjuste]

If you'd mix Potassium ferricyanide with one of those acids, would it liberate toxic gas ?

[@joshsmit779]

I actually remembered log rules.

[@Josafit]

Excuse me professor 🙋‍♂️... can I go to the restroom 🚽. I be back

[@Socratica]

Okay but be quick about it! ⏲️ Here's the hall pass. 🔖

[@anat175]

Thanks for the GREAT video ! I felt like i have to test the pH levels of my stuff at home such as : Drinking water, Beauty products. thank you for providing the link to Amazon and Coupon code for Rozway digital pH Meter in the description of this Video

[@Socratica]

We're so glad you enjoyed it! We want to run around our house testing everything now. This little pH meter is great!! :) Thanks for watching. :)

[@filipve73]

Is there a Asymmetry in the pH scale and if so which one has the overhand the acid or the base? (maybe there is also a link to Avogadro constant?)

[@sumanmeena365]

Great job dear..u r the best tutor ever..vth luv from India..😍

[@juliecyris]

Great video! Would milk be a colloid rather than a suspension?

[@knowingchemistry735]

I have a doubt here...why shampoos are soapy /slippery to touch but they are acidic in nature ?? Kindly help me with this one...

[@daninhagaspar3929]

Thank you so much for the video!

[@Socratica]

You are so welcome! Thank you for watching! 💜🦉

[@frankcrawford416]

Are bases considered alkaline? Thanks

[@Socratica]

Yes! Good Question! Basic and alkaline are synonyms - they mean the same thing. Thanks for watching! :)

[@thelightone1467]

hey i have a question if i post some pics in the discripion can someone tell me what they are they are chemical formlas i think i found them painted to a bridge near my house and cant figure out what they mean plz someone help

[@jebuscoyoteaj6182]

what could i fine with a very high ph ?? I have testing strips for finding the ph of things and I really want to make one into the purple!

[@Socratica]

FUN!! Do you have any drain cleaner? Those are usually made with strong bases. Be very careful with this (we recommend using eye protection and wear gloves). Thanks for watching! 💜🦉

[@SouthernSierra56]

It's that salicylic acid that you have to watch out for.

[@dharaitamil6469]

Very nice teaching mam

[@joelgriffiths6668]

Great video, I love the channel Well done

[@dantec8854]

Can i use the tester on exterior surfaces with stains

[@Socratica]

What an interesting question! This tester works best with a liquid sample you can immerse it in. So unlikely, unless you could scrape up some of it and put it in water to dissolve it (measure how much water so you know how dilute it is) and then take the pH?

[@shahidansari8055]

Wah. Verry good video🌟🌟🌟🌟🌟 thanks,

[@MRSDR100]

Q: What did the lemon say to the window cleaner? A: Why you so basic though?

[@Socratica]

We are so stealing this joke.

[@sheldonsenft6513]

It's been a long day at school, but I'm sorry --- I don't get it. Oh, and by the way, we loved watching your video - well done!

[@bellenesatan]

Sheldon Senft window cleaner= alkaline. Alkaline=basic. Get it?

[@thomasgronek6469]

Meg, Sorry , I don't get it.

[@Ptiou99]

@@thomasgronek6469 The window cleaner is considered a base (basic) because it has less Hydrogen ions (H+) than water, the lemon is considered an acid (acidic) because it has more H+ ions than water...hence the joke

[@lVlandiz]

I didn't want to to go to California Colorado where's it at

[@hpspspspsps5798]

what does it mean when an hcl solution has an h+ concentration of 10 power -8?

[@drumetul_dacic]

It means that it is a base with a pH of 8.

[@hpspspspsps5798]

Daniel Șuteu but isn't hcl an acid? My textbook gave a weird conclusion. Says the ph is 6.9 because an acid can't have more than 7.

[@omkaryawale6206]

Dosent soda have Carbonic acid?

[@Mullet-ZubazPants]

Should have told her that healthy skin is slightly acidic. Her head would've exploded

[@joshsmit779]

H=10^(-pH)

[@thomasgronek6469]

Nicholas Williams: I think you won the prize, an H+ molecule. It's in the mail (hahahaha)

[@raima9264]

everyone here be like thank u this helped me so much for my mid-terms or gcse or a levals me be like am i ment to be learning this cuz like mate i just joined middle skl.😅😂

[@Socratica]

NICE!! 💜🦉

[@oliverhees4076]

Sriracha is hardly spicy (try Sichuan food).

[@Socratica]

hehehehe we have! Thought we were going to DIE. We might actually be dead now. It was shocking! This is the first Sichuan place we ever went to: www.laweekly.com/restaurants/chung-king-99-essential-restaurants-2011-2172816 Sadly it's closed now...

[@vojtechvaligura7054]

I believe milk is acidic due to the presence of lactic acid.

[@kunslipper]

Thank you so much.
