To 1 M solution of AgNO_(3), 0.75 F quantity of current is passed. What is the concentration of the electrolyte, AgNO_(3) remaining in the solution?

Answer»

Solution :Given : Initial concentration of
`AgNO_(3)=1M=1N`
Quantity of current = 0.75 F
Formula :
`""` 1 Faraday = 1 equivalent mass
Solution :
For 1 F current In `AgNO_(3)` will be liberated.
For 0.75 F current 0.75 N `AgNO_(3)` will be liberated.
The concentration of `AgNO_(3)` REMAINING
`""=1.0-0.75`
`""` = 0.25 N
`therefore` The concentration of `AgNO_(3)` remaining
`""`= 0.25 M
