Question

How many atoms will be disposited on when 1 amp electricity passes through cu++ solution for 1 min

Answer 1

Answer:

Explanation:

from

m=I*t*elecrochemical equivalent

but,

z=Ar/v*1 F

z=63.5/2*96500c

therefore: electrochemical equvalent of cu =0.001136

then from,

mass deposited=I*t*z

m= 1amp*60sec*0.001316

mass of copper deposited =0.68 grams
