Question

4 multiple choice 10 points when aluminum reacts with copper (ii) chloride, does it replace the cation or the anion? cation (copper) anion (chloride) both neither

Explanation:

This is a single-displacement reaction. Aluminum is more reactive than copper in the metal activity series, so it will displace the copper cation (Cu²⁺) from copper(II) chloride, forming aluminum chloride and copper metal. The chloride anion (Cl⁻) remains as part of the product compound.

Answer:

Cation (Copper)
