Question

how many grams of silver could be plated out on a serving tray by electrolysis of a solution containing silver in plus one Oxidation state for a period of eight hours at a current of 8.4 amperes.what is the area of the tree if the thickness of the silver plating is 0.0025 cm and density of silver is 10.5 gram per centimetre cube .?​

Answer 1

ℏ✺ℓᾰ ժḙᾰԻ.

quality of electricity passed,

= 8.46 × 8 × 60 ×60C

amount of silver deposited,

= 107.8/ 96500× 8.46 × 8 × 60× 60

= 272.18g

volume of silver= 272.18 /10.5

= 25.92 cc

area of tray = 25.92 / 0.00254

= 1.02 × 10^4 cm^2
