Question

Aqueous copper (ii) ion reacts with aqueous iodide ion to yield solid copper (i) iodide and aqueous iodine. write the balanced net ionic equation. express your answer as a net ionic equation. identify all of the phases in your answer.

Answer 1

To answer this question, you just have to translate the chemicals into their chemical formula. Then, indicate the state of phase as described. The net ionic balance equation is as written below:

2Cu²⁺(aq) + 4I⁻(aq) → 2CuI(s) + I₂(aq)

aq is in aqueous phase
s is in solid phase
