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.

[@noahriding5780]

I agree! very fascinating. Thanks.

[@bizzarepaintisbetterthanclix]

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

[@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.

[@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

[@noahriding5780]

does this mean someone could actually make their own really large batteries to use for say housing solar stuff? or can you actually get enough power for that to work?

[@Science.Buddies]

It would take a very large battery - please see the link in the video description for more background information.

[@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!

[@juliusfucik4011]

You can also use alumium foil and a graphite pencil "lead"

[@eddieriesgo1451]

Thanks for sharing your knowledge..

[@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!

[@juliusfucik4011]

Set it to mA.

[@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

[@LyamGuadian]

Can you help explain how to record the Short circuit current section of the table? Thank you.

[@Science.Buddies]

Please see the written instructions linked in the video description.

[@alexanderpankevicz3738]

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

[@anubisplays1421]

Brass plated screws and zinc plated screws work

[@laurensoq9126]

Does this create Cl2 gas?

[@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.

[@Sterusy]

in what voltage does that buzzer operate?

[@Science.Buddies]

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

[@kayotpatrimonio4839]

can you recharge this type of battery?. .

[@Science.Buddies]

That's an interesting question! Generally, saltwater batteries are rechargeable if they have a reversible chemical reaction.

[@Emerson-p3x]

A question that came to me now was: what if we take several Daniell batteries (those that are submerged in water and salt) and connect them in series, like 8 cells in a circular format, in which we interconnect the circuit with another cell of the same type as the others, Where would electrolysis occur? Like, where would the top of the electrical potential (anode) be? Sorry if the writing was bad, I don't speak English and I used a translator.

[@Science.Buddies]

Hi - voltage is a potential difference defined between two points. This means that to measure voltage at any point in a circuit you must first choose a reference point that you define as zero volts. Normally in a circuit with a single battery, we choose the negative terminal of the battery as zero. So for example if you have a circuit with a single 9V battery and define the negative terminal as 0V, then the positive terminal would be +9V relative to your reference. However, you could just as easily define the positive terminal as 0V, and then the negative terminal would be -9V relative to the reference. The same applies if you continue connecting batteries in series (and eventually loop them back around in a closed circuit) - you can choose any point in the circuit as the reference voltage.

[@Emerson-p3x]

@@Science.Buddies Thank you for answering my question, but if it doesn't bother you, could you answer one last question? Basically it goes like this: imagine you have a circle like this: (all are Daniell cells in an aqueous medium) + - + - - □□□□ + + □ □ - - □ □ + + □□□□ - - + - + each small square represents a cell, now imagine that they are all connected in series, how would we know in which cell the electrolysis will occur? for example: I have an incomplete square like this: + - + - + □□□□ - □ +□ - □ □□□□ + - + - And now we close it with another cell like this □□□□□| + □ | □ □ □ | □□□□□| - (Imagine that (|) are the wires.) The electrolysis of the middle cell will be carried out because I connected the point of highest potential with the lowest using this cell, so this cell remains something external to the battery. In other words, electrolysis occurs in the place where the electric current began to pass So there is another question: if I separate the two parts of the battery [ ] and put them together at the same time [ ] , where will electrolysis occur? After all, I started the electric current at 2 points. I'm sorry if I don't understand and again: thanks for responding.

[@Science.Buddies]

Hi - this is a little more support than we can provide in a KZbin comment. We recommend looking for dedicated forums about chemistry or electronics to find an answer to your question.

[@Emerson-p3x]

@@Science.Buddies ok, thanks for responding

[@chetan98250]

Not generate enough amp, to ring buzzer

[@gilgamesh6135]

Did you ever solve the problem

[@chetan98250]

No

[@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!

[@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).

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_
