A current of 1.5 A passes through an electrolyte for 15 minutes. Calculate the mass of copper deposited if the equivalent weight of copper is 31.75 g/equiv.
💡 Hint: Use the charge calculation to apply it to the mass deposition.
In a laboratory, an experiment is conducted where various salts are electrolyzed for the same charge. If 0.5 g of lead is deposited, find out how much barium weighs if its equivalent weight is 137 g/equiv.
💡 Hint: Set up the ratio based on their equivalent weights to find the mass of Barium.
