To one molar solution of a trivalent metal salt, electrolysis was carried out and 0.667 M was the concentration remaining after electrolysis. Calculate the quantity of electricity passed.

Answer»

Solution :Given : Initial concentration of the solution
`""=1M`
The concentration REMAINING after electrolysis
`""=0.667 M`
Solution :
`therefore` The amount deposited `=1-0.667 M`
`""=0.333M`
1F = FARADAY = `3 times 0.333 M`
`""=0.999 M`
`""=1M`
`therefore` 1 Faraday current is used.
