Electrochemical equivalent is the amount of substance which gets deposited from its solution on passing electrical charge equal to :

Options

A. 96,500 coulomb
B. 1 coulomb
C. 60 coulomb
D. 965 coloumb

Answer

To solve the question regarding the electrochemical equivalent, we need to understand the definition and the relationship between current, time, and charge. Here’s a step-by-step breakdown:

### Step 1: Understand the Definition
Electrochemical equivalent (E) is defined as the amount of substance deposited from its solution when an electric charge is passed through it.

### Step 2: Recall the Formula for Charge
The charge (Q) can be calculated using the formula:
\[ Q = I \times T \]
where:
- \( Q \) is the charge in coulombs,
- \( I \) is the current in amperes,
- \( T \) is the time in seconds.

### Step 3: Substitute the Values
According to the definition of electrochemical equivalent, we consider:
- Current \( I = 1 \) ampere,
- Time \( T = 1 \) second.

Substituting these values into the formula:
\[ Q = 1 \, \text{A} \times 1 \, \text{s} = 1 \, \text{C} \]

### Step 4: Conclusion
The amount of charge that corresponds to the electrochemical equivalent when 1 ampere of current is passed for 1 second is 1 coulomb.

Thus, the answer to the question is:
**1 coulomb**

### Final Answer
The electrochemical equivalent is the amount of substance which gets deposited from its solution on passing electrical charge equal to **1 coulomb**.
