Expert Answer:
a) As silver is deposited on the electrode from AgNO3 solution,
Ag+ + e- → Ag(s) ................................reduction
Atomic mass of Ag = 107.8u
b) 2 H2O → O2 + 4H+ 4e-
4 moles of electrons are required to deposit 1 mol O2
Therefore, mols of O2 librated = moles χ molar mass = 0.0025 Χ 32 = 0.08 gm
