Silver is removed electrolytically from 200 ml of a 0.1N solution of A...
Given:
Volume of solution (V) = 200 mL = 0.2 L
Normality of solution (N) = 0.1 N
Current (I) = 0.1 A
To Find:
Time taken to remove half of the silver from the solution
Formula:
The amount of substance (m) can be calculated using the formula:
m = N * V
The charge (Q) can be calculated using the formula:
Q = I * t
The amount of substance (m) can also be calculated using the formula:
m = Q / F
Where F is the Faraday constant and is equal to 96500 C/mol
Solution:
First, let's calculate the amount of silver in the solution initially:
m1 = N * V
m1 = 0.1 * 0.2
m1 = 0.02 moles
Now, we need to calculate the amount of silver to be removed to reach half of the initial amount:
m2 = m1 / 2
m2 = 0.02 / 2
m2 = 0.01 moles
Let's calculate the charge required to remove this amount of silver:
Q = m2 * F
Q = 0.01 * 96500
Q = 965 C
Now, we can calculate the time taken to remove this charge using the formula:
Q = I * t
t = Q / I
t = 965 / 0.1
t = 9650 seconds
Therefore, it will take 9650 seconds to remove half of the silver from the solution.
Answer:
The correct option is 4. 9650 sec.
