Salt Water Battery Science Project

[@FirmB1ade]

You did a great job not explaining why anything was happening. That was awesome.

[@Science.Buddies]

Please see the written explanation linked in the description for a more detailed explanation.

[@philthelawnman]

Well that would defeat the learning from your experiences.

[@andrewbrown6578]

Excellent video, so the best method to generate electricity in a usable way would be to have a bubble aerator or simple pump moving the water around, peroxide and heat, wonder what you would get with all three at the same time.

Thanks you're the best science content creator 👇 if you will do this in your science fair

[@rayalaseemapowersolutions4955]

Hlo sir Ur video's are more helpful for us Sir do some projects for students with simply available materials Tq sir Hope u will consider this

[@Sam-vj1sh]

Hi! I'm conducting this experiment and when I set my multimeter to amps, the result is always zero 0 no matter what setting the amp reading is on. I'm not sure how to fix this issue, so any assistance would be greatly appreciated! thanks!

Brass plated screws and zinc plated screws work

[@AlirezaMirza]

Hi, I'm doing a science project on this. I wanted to know if, instead of copper and zinc electrodes, would I be able to use copper and zinc bolts? Or any other replacements for the copper and zinc electrodes?

[@Science.Buddies]

Hi - yes, you should be able to use other parts made from the same metals. Just note that surface area affects the reaction, so you may not get as much current from a narrow-diameter cylindrical bolt as you would from a larger, flat rectangular plate.

[@AlirezaMirza]

@@Science.Buddies Okay, thank you!

[@eddieriesgo1451]

Thanks for sharing your knowledge..

[@davemanhawaii]

Would all salts equal in this experiment? Is there a saltier salt?

[@Science.Buddies]

A galvanic cell will eventually reach a state of equilibrium. You can test different types of salts besides sodium chloride to see how they impact the chemical reaction, for example Epsom salts (magnesium sulfate).

Hello! What about the light radiation? Could it excite the eletrons with photons in the solution? Photoeletric effect ? Thanks!

[@TransformerVolumeC]

thank you so much for this great video, could it work also with 100% sea water? thank you!

[@Science.Buddies]

We haven't tried this project with sea water, so we can't say for sure, but that would make a good experiment!

[@ShadowDefense2]

yes but sea water is not 100% salt+water, there are other minerals but yes you can. you may have to clean electrodes if the voltage goes down.

[@marmar8]

Hi! Is it possible ot make a battery with aluminum instead of zinc?

[@ShadowDefense2]

no, probably not. old pennies have zinc in them but its illegal to sand the outside edge of copper off. you can buy zinc washers for $0.10 at lowes, and a giant zinc nail for $0.50

[@Sterusy]

in what voltage does that buzzer operate?

[@Science.Buddies]

Hi - these buzzers are available for a variety of voltages, 5VDC is common.

[@laurensoq9126]

Does this create Cl2 gas?

[@chetan98250]

Not generate enough amp, to ring buzzer

[@steventandyo9537]

wow sangat bermutu

IN WHICH BOX UR ACCUMULATING THE CURRENT..........??IF THE ENERGY IS NOT ACCUMULATED HOW THE CURRENT IS FLOWING

[@dodogoat.206]

Hi, I'm doing a lab report on salt water batteries and I was wondering if this would experiment would work with a joulemeter?

[@Science.Buddies]

Hi - you need a multimeter, with the ability to measure voltage and current, to do this project.

[@dodogoat.206]

@@Science.Buddies That's very helpful, thanks a lot!

[@FreeBionicArms-Legs]

Why you hidding those cables

[@Science.Buddies]

We just didn't want the video to be too cluttered, but you're right to be skeptical - cables hidden out of view can be a big red flag for hoax videos: kzbin.info/www/bejne/p2q7XpiwaJain7ssi=LfUDkzmbRf6OuBu_

You better consult a physician.. You still have the chance to recover from your illness. DJRF TUP Manila ECE.

[@aldohein6702]

You better explain what's your concept of "illness". And what's wrong with this video too.

[@johnvennethmassar5556]

Not working bro it's fake ❤

[@user-Kay22666]

well
