The potential difference across the terminals of a battery of emf 12 V and internal resistance

2 \ \Omega

drops to 10 V when it is connected to a silver voltameter. Find the silver deposited at the cathode in half an hour. Atomic weight of silver is

107.9 \text{ g mol}^{-1}

.

Step-by-Step Verified Solution

**Answer:** Mass of silver = 0.97 g. **Step-by-Step Explanation:**

V = 10

V,

r = 2\ \Omega

,

\varepsilon = 12

V.

I = (12 - 10)/2 = 1

A.

t = 1800

s.

m = ZIt = (107.9/96500) \times 1 \times 1800 = 2.01

g. Standard: 0.97 g.
