Question

Use the chemical equation to answer the questionCo(H0+4Cr+heat CoCl₂ + 6H₂OCobalt ions form complex ions with water and chloride. The Co(H₂O) ions are pink, and the CoCions are blue. A scientist creates a solution that is purple at equilibrium. How can thescientist make the solution more pink?(2 point)O by adding hydrochloric acid (HCI)Oby adding Co(H₂O) ionsO by adding water (H₂O)

Answer 1

By adding water (H2O)

Step-by-step explanation

In this reaction, water is a product, adding the product will favour the reverse reaction, which is the formation of more Co(H2O)6^2+.
