Question #117dd
1 Answer
2.9M
Explanation:
- The current passed,
# I=10 A# - The time of passing the current,
#t=16 min 5 s=(16xx60+5) s = 965 s# - So the quantity of electricity passed is
We know from Faraday's law that the passage of 1 Faraday of electricity accumulates 1 gm-equivalent ions (here
So, in our case 0.10 gm-equivalent
Since
{since
Now, the initial concentration of the solution is 3 M.
Its 0.5 L will contain
After deposition of 0.050 mol due to passage of electricity, there will be
Hence the final concentration after electrolysis is
