andre [41]

Answer:The purple color is due to a mixture of the pink aqua complex and blue chloro complex and is not due to a new species.

Explanation:

A change in chloride or water concentration could shift the equilibrium towards any of the species causing its colour to become the dominant colour of the solution.
