An oxide of metal (at . Wt = 112) contains 12.5% of oxygen by weight. What is the valency of metal? What mass of the metal will be liberated when the oxide is converted to chloride with HCl and electrolysed using a current of 9.65 amp for a period of 30 min?

Text Solution

AI Generated Solution

To solve the problem step by step, we will break it down into two parts: finding the valency of the metal and calculating the mass of the metal liberated during electrolysis. ### Step 1: Determine the Equivalent Weight of the Metal Given: - Atomic weight of the metal = 112 g/mol - Percentage of oxygen in the oxide = 12.5% - Atomic weight of oxygen = 16 g/mol ...
