Adding powder cu and zn to a solution containing 1.0 m is each of cu2+ and zn 2+ ions would result in the formation of

Answer 1

Adding powder Cu and Zn to a solution containing one molar each of Cu²⁺ and Zn²⁺ ions would result in the formation of Cu and Zn²⁺.

• Since zinc lie above copper in the activity series of metals, zinc can reduce Cu²⁺ to copper and itself get oxidized to Zn²⁺ while the reverse reaction is not feasible.
• Hence, Cu and Zn²⁺ originally present remains as it is while the Cu²⁺ is reduced by zinc forming more of Cu and Zn²⁺.
