Question

Answer 1

How DC current changes the composition of solution ?

Answer 2

i know it separates the ions into cations and anions in solution !

Answer 3

but how?
Why AC current can't?

Answer 4

i got it now !

Answer 5

sorry ! for disturbing you :(

Answer 6

do you want to know how did i get this ?

Answer 7

Answer 8

Yeah no problem you're not disturbing me. I was reading into it a bit. Yeah, I see from what I know it's going to be different for DC and the same for AC.

Trying to figure out the most straight-forward way to explain this.

I found a great explanation though check it out:

Direct current means a positive terminal (cathode) at one end of the solution and a negative terminal (anode) at the other end.

"Now there is an electric potential established between the two terminals or plates. Hence, due to the electric field, the ions in the solution will travel towards the plates. Negatively charged ions in the solution will travel toward the cathode. Positively charged ions will travel towards the anode. The ions will get deposited on the plates and then charge disappears. These ions may react with the metal on the terminal plates and form different compounds.

Hence the number of ions will get reduced in the solution. The concentration will decrease and hence the reactivity also changes.

Thus the composition will be changed. After a long time, the ions will all get deposited and the solution will not have any more. Then no current will pass.

If an alternating current source is connected, then the potential will change direction alternately. Hence the ionic composition will remain same. The ions will get generated, deposited and again they get dissociated from the plates. This will happen for some reversible reaction based ionic compounds. (rechargeable batteries)."

Yeah @mayankdevnani how did you get that answer?

Answer 9

lol ...same solution from brainly

Answer 10

this solution actually made me understand and see coincidence,you typed that same

Answer 11

It's been sometime since i've done that stuff. but his explanation was great. lol that's very strange.

Answer 12

we could even try to summarize this even more so we understand it better

Answer 13

so how could you summarize this ?

Answer 14

Yeah, I try to simplify things in my own words. I actually didn't understand this well enough to explain it properly.

to me it seems that he's saying this:

DC when the ions deposit on the plates, they can react to form different compounds, this would lower the concentration of ions we have/change our composition.

For AC he says something interesting: the ions get deposited on the plates, and dissociate from the plates.

Answer 15

we can also say that AC current has not its own positive and negative terminal ,so it can't store much energy to provide potential difference to change the composition of solution

Answer 16

btw it can't store

Answer 17

yup

Answer 18

that's strange we looked at the same explanation online

Answer 19

it's better explanation

Answer 20

I'll be on later. Cheers hope I helped

Answer 21

thank you photon
you are awesome <3
