Is a compound that went through a chemicAl change
I think the correct answer would be because copper has a lower activity than hydrogen and cannot replace the bonds in it. Substances that are not oxidizing do not react with copper since the redox potentials are very low. Hope this answers the question.
I think it would be B maybe
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:
The pink aqua complex of cobalt can be in equilibrium with blue chloro complex of cobalt giving rise to a purple colour. This equilibrium is governed by Le Chaterliers principle. 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.
