The quantity of electricity required to liberate 0.1 g equivalent of an element at the electrode is

Options

A. 9650C
B. 96500C
C. 965C
D. 96.5C

Explanation

To solve the question regarding the quantity of electricity required to liberate 0.1 g equivalent of an element at the electrode, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Gram Equivalent**:
- The gram equivalent of a substance is the amount of that substance that will react with or replace one mole of hydrogen or one mole of electrons in a reaction.

2. **Identify the Quantity of Electricity for 1 Gram Equivalent**:
- It is known that 1 gram equivalent of a substance requires 96500 coulombs of electricity to be deposited or liberated at the electrode.

3. **Calculate the Quantity of Electricity for 0.1 Gram Equivalent**:
- Since we need to find the quantity of electricity for 0.1 gram equivalent, we can use the following calculation:
\[ \text{Quantity of electricity (Q)} = \text{(Quantity of electricity for 1 gram equivalent)} \times \text{(Number of gram equivalents)} \]
\[ Q = 96500 \, \text{C} \times 0.1 = 9650 \, \text{C} \]

4. **Conclusion**:
- Therefore, the quantity of electricity required to liberate 0.1 g equivalent of an element at the electrode is **9650 coulombs**.

### Final Answer:
The quantity of electricity required is **9650 coulombs**.
