Question on: JAMB Chemistry - 2024

The quantity of electricity required to deposit 180g of Ag from a molten silver trioxonitrate(V) is

[Ag = 108]

A

1.08F

B

3.30F

C

1.67F

D

1.80F

Ask EduPadi AI for a detailed answer
Correct Option: C

1. Half-reaction: Ag+ + e⁻ → Ag

2. Moles of Ag = 180 g / 108 g/mol = 1.67 mol

3. Quantity of electricity: 1 mole of Ag requires 1 Faraday, so 1.67 moles require 1.67 Faradays.
