attempt please 🙂 what are the underlying reactions?

[violet frigate]

those are my module questions 😭 i cant understand anything 💀

[violet frigate]

i didnt understand the part "preparing 12% cd-hg on a cathode of 2g hg"

what equation do i form from that

ohhhhhhh theek haiii

do you have the link?

🫠

[fringe fern]

mass/mass %

mass of solute by total mass of solution x 100 g

so 12 = x/(x + 2) x 100 (since the deposition happens on the electrode, increasing its mass)

[violet frigate]

what if we consider it like:
12 g of cd and 88g of hg or 88g of cd and 12 g of hg

[fringe fern]

na it is 12 g of Hg-Cd (thta is an amalgum)

in 100 g of solution

but

it is given that the solvent is 2g

so you take this x thingy

[violet frigate]

nahhh like i dont wanna take the x

if it was 12g of cd in 88g hg then we take it for 2g of hg and vice versa

would it be 12g cd or 12g hg

[fringe fern]

sure, means the same thing

and you are depositing Cd right so 12% refers to Cd

also, it should be CdCl2 in the q right Ca doesnt fit

[trail igloo]

yaha Cd ka source kya hai tho (dumb question? idk electro padhi nahi bohot time se 🤡)

[violet frigate]

ohhhhh okay okay

[violet frigate]

wym

[trail igloo]

kis cheez ki dissociation se Cd metal produce ho rha?

CaCl2 toh calcium dega na

[violet frigate]

cdcl2 hai wahan pe q galat hai

[trail igloo]

accha

[violet frigate]

yeah yeah it is cdcl2
