I'm over joy of your presentation and clear English. Thanks you. I'm studying environmental engineering. I will always follow you sir.

[@channe149]

When was this video shot? Has such a soothing 90s vibe to it. Also, very explanatory and simple.

[@abdulhadialreheili2463]

Excellent illustration! Thanks for this guide, it shall come in handy for tomorrow's midterm :)

Thanks for this video 👏😴 Kal Practical hai mera.. saal bhar gya nahi Lab mein aur aaj ye mil gya Dhanyawad ❤

[@callistonian9315]

Brilliant. I can't believe I never thought of using my mouth to operate the graduated pipette. Just sip some of that sweet, sweet ammonia. I mean, who needs to see the volume reading anyway?

[@Charlie-sx7dk]

Callistonian omg i can smell the ammonia emanating from the glass bottle already 😷

[@patrycjaprzedwojska1072]

made my day

[@marrrcelo]

shit negro thats certainly stupid, even though some guy could do it wrong and get a bad moment

[@allanjaymartirez]

7:24 minutes; is it a good practice to suck the reagent to fill the pipette? Or should you use an aspirator? However, i've seen more. In my work place before, there is this guy who knows everything. When i asked him to determine if our water has conductivity, he tasted it first if it was salty. Sigh, how i wish i added sodium cyanide to the water first.

Is there any video about gross alpha and beta radiationa analysis in water? Thanks

Thank You sir, Explained Wonderfully (y)

how calm, i went to sleep while watching it with background music on🤣😍

[@hanakurd1795]

I wished you could explain the nutrient in water too, such as nitrate, sulphate, and phosphate.

[@rajneeshpatel4786]

Gorgeous explanation and content thank sir upload more lecture

[@rafisalim9478]

Thank u sir ur way of speaking is very good. I can easily understand but m so week in lab works

[@jaxim8520]

Same here

[@sandeepvamsi8540]

thank you sir, this video helped me a lot, you told the process in a simple way, i hope you put more videos which will be helpful to the students like us. very very thank you. superb

[@atiyakazi1433]

You teach really very well sir 🙂

[@TakFaizan]

If anyone is watching different videos of this test on youtube, I want to tell them that this is the best video among all videos on youtube

[@michaelkiap3604]

Allan J Martirez, the guy's assumption that elevated conductivity means salty taste can be misleading. Also depending on the pH of the water, sodium cyanide can be quite innocuous.

[@sharif0093]

What's the use of the loud music in this experiment 😢

[@sowmyasree3978]

Why do we add ammonia buffer solution

How to prepare EDTA solution

[@buddhamsarnamgachchhami4820]

Background music 👍👍

[@sahityasahu7357]

Thanku so much sir explain brilliantly 🙂🙂🙂

[@bhavaniputsala]

According to me, we shouldn't add distilled water to boiled and cooled water..since the volume will change but no salt is increased and this reflects in different answer for permanent hardness because hardness is also dependent on volume...i.e suppose there is equal amount of permanent hardness causing salt in two samples of hard water with different volumes then permanent hardness in ppm or mg/lit is different for both the samples...so instead off adding distilled water we can measure the amount of water remained after boiling and calculate with the same.

[@dr.v.d.jindal8581]

What if the colour of solution is not turning to blue i.e. remaining same...plz tell what is wrong i am doing..?

[@ishapatel1460]

Sir, I have doubt is this test require fresh sample or we can use any sample like 1 week old?

[@licious4633]

I don't actually get the part of adding distilled water to sample water.Yes both of them the temporary hardness has been removed.Instead he would have added additional boiled sample water instead of distilled water.

[@KingKhan-bi7kb]

Sir when we r adding distilled water to the boiled water then there will be some temporary hardness of that distilled water which in turn produces some temporary hardness in the water. Then how can we proceed the reaction further. Please clarify my doubt as soon as possible.

[@Charlie-sx7dk]

Mujahid Khan I think he meant to say deionized water

[@navedshaikh4822]

There is no impurities in distilled water..

[@Silentkiller-ro4oo]

Music kyo add Kiya h vedio m

[@milonchandra796]

What is the molarity of EDTA solution

[@AbdulRahman-rd8jb]

Sir, Please do not pippetout AMMONIA BUFFER and transfer the sample in to conical flask by using pippete and not measuring jar..Hope you oblize. .he presentaion is very excellent. suggetion by the SENIOR ANALYST in Govt of AP.

[@priyafreddy2013]

What is the normality of EDTA used pls reply

[@ChallHatt]

This is better than watching Indian Idol on TV

[@cheethapavan874]

good and clean explanation sir ,thank you.

[@metsor7066]

what is generally higher in domestic water temporary hardness or permanent hardness

[@nik..official4825]

thanq sir aaj pahli bar chemistry me pura experiment samajh aaya hai

[@dhruvdd17]

what is that background music, so depressing😭😴

[@atulyadav3846]

Pleas, upload a video on o henary method for estimation of hardness of water.

[@devendrakulkarni178]

Sir poison deactivate process

[@muhammadwaqas1323]

calculate the hardness and the concentration of chlorides in wastewater sample. Express your results in mg/L Volume of waste water sample = 0.15 Liter. Volume of AgNO, used for titration 225 ml. Volume of EDTA titrant = 8500 micro L Molarity of EDTA = 15 mM, Normality of AgNO, O.O5N...solve this problem

[@tigihaile4345]

I got all that i learn at school and thank you

[@allanjaymartirez]

Well explained though, thanks for posting this

[@loverofyahshua]

My volume cannot be heard, it is very low volume. Is he saying, BOILING?

[@ebrahimlari9241]

Does pH affect water hardness? for instance, changing from 7.5 to 6 or 9.

[@serakahyaoglu1556]

does this also work for sea water?

[@cheelavishnu7312]

Sir how to reduce hardness in water

[@hemabeverages2485]

Sir, I thank you very much for the vedio, i have some doubt where did you find the preparing reagents procedures. bcoz i am seeing diffrent chemicals used for preparing reagents.

[@hemabeverages2485]

do you have procedure for how to determine calcium hardness

[@kusapago]

Mention reference used

[@mysteryman9613]

Color test of water plz make a video on this topic

[@nageshchary4572]

thanks for this video.. this helps me for practical exam

[@icedsolid]

What purpose does the hydroxylamine hydrochloride have in the eriochrome solution?

[@MegaCadette55]

+icedsolid I think it is to regulate the pH.hydroxylamine hydrochloride is also known as tris buffer. buffers are used to prevent pH changes

[@icedsolid]

Much appreciated - Thank you! You taught me something new. I presume for a water sample this gets put in excess then because of different pH ranges and buffering capacities?

[@MegaCadette55]

icedsolid I am so sorry I might have confused hydroxylamine hydrochloride with tris hydroxylamine hydrochloride buffer. The later is what I am familiar with and is the one used to regulate pHs. I am not familiar with the former. sorry, please ignore everything I said !

[@nasraaspari6282]

Can i ask how to solve the concordant reading? Thank u

[@riteshbadhani2625]

if two reading are exactly same , it is concordant.

OMG DID HE JUST... Once my prof. told me that she had used her mouth to pipette but damn...

[@vijaysabarish9600]

what is the standardization of EDTA soln please I need it for my work im doing on hardness of water

[@bhavaniputsala]

by adding hardwater with known amount of salts in it [actually we prepare standard hardwater in laboratory for standardisation of EDTA] we find out the molarity of EDTA we have.. that is called as standardisation of EDTA
