Question

What single reagent would you use to seperate

Cu2+from Ag+? Write equations that show what
happensto one or both, whichever is appropriate.

Answer 1

The reagent is HCl.

Step-by-step explanation:

To separate Cu²⁺ from Ag⁺ in solution, we can use HCl since it forms an insoluble chloride, AgCl, while the Cu²⁺ ions remain in solution. This can be represented by the following equation:

Ag⁺(aq) + Cu²⁺(aq) + Cl⁻(aq) ⇄ AgCl(s) + Cu²⁺(aq)

`Kps_(AgCl) = 1.77\cdot 10^(-10)`
