Questions & Step-by-Step Solutions

In electrolysis, if 1 mole of electrons is transferred, how many grams of copper can be deposited from Cu²⁺?
  • Step 1: Understand that in electrolysis, when we transfer 1 mole of electrons, it can reduce 1 mole of Cu²⁺ ions.
  • Step 2: Know that the molar mass of copper (Cu) is 63.5 grams per mole.
  • Step 3: Since 1 mole of Cu²⁺ is deposited when 1 mole of electrons is transferred, it means we can deposit 1 mole of copper.
  • Step 4: Therefore, the amount of copper deposited is equal to the molar mass of copper, which is 63.5 grams.
