Question
The two aqueous solutions; A (AgNO3) and B(LiCl) were electrolysed using Pt. electrodes. The pH of the resulting solutions will
Options
A.increase in A and decrease in B
B.decrease in both
C.increase in both
D.decrease in A and increase in B.
Solution
AgNO3 At cathod :
Ag+ + e- → Ag(s)
At anode :
2H2O → O2 + 4H+ + 4e-
∴ At cathode pH will increase.
Ag+ + e- → Ag(s)
At anode :
2H2O → O2 + 4H+ + 4e-
∴ At cathode pH will increase.
