Electrolysis

Step 1: Concept
. One Faraday (96500 C) deposits one equivalent weight of Ag.
Step 2: Analysis
Equivalent weight of Ag = 108 g.
Step 3: Calculation
96500 C deposits 108 g of Ag. 965 C will deposit .
Final Answer: (D)

Step 1: Understanding the Concept:
Use Faraday's first law: .

Step 2: Detailed Explanation:
Equivalent weight of Ca = Atomic weight / valency = 40 / 2 = 20.
g, A.

seconds.
Convert to hours: hours.

Step 3: Final Answer:
16 h

Step 1: Understanding the Concept:
Faraday's first law of electrolysis: , where is mass deposited, is electrochemical equivalent, and is charge.

Step 2: Detailed Explanation:
Given C. Using , we get . So, the mass deposited (m) is equal to the electrochemical equivalent (Z).

Step 3: Final Answer:
1 C electricity deposits the electrochemical equivalent of Ag, which corresponds to option (B).
