During electrolysis 5g of a metal E was deposited by passing a current of 200Ampere for 30mins across the solution of E. find the ionic charge of E

To solve this problem, we need to use Faraday's laws of electrolysis. Faraday's laws relate the amount of substance deposited during electrolysis to the quantity of electricity passed through the solution.

Step 1: Calculate the total charge ($Q$) passed.
The current ($I$) is $200 \text{ A}$.
The time ($t$) is $30 \text{ minutes}$. We need to convert this to seconds.

$$t = 30 \text{ min} \times 60 \text{ s/min} = 1800 \text{ s}$$

The total charge ($Q$) is given by the formula:

$$Q = I \times t$$ $$$$
