Same amount of current was passed though silver nitrate and sodium chloride solution connected in series. At cathode 0.35% hm silver was deposited.What amount of sodium would be deposited in the same time at the cathode?(Ag=108,Na=23)
The molar mass of Ag is 108 g/mol. Let n be the number of moles of hydrogen liberated
2H +2e −→H2
Thus 1 mole of hydrogen corresponds to 2 moles of silver.
