Answer 2

Answer:

The aqueous solution of transition metal salt changes colour from pink to blue, when concentrated hydrochloric acid is added to it. The change in colour is due to

1. equation of hydrogen that changes the oxidation state of the metal icon.
2. change in the coordination number of the metal icon ham 6 to 4 and formation of new species in solution.
3. formation of a coordination complex of the metal icon with hydrochloric acid.
4. protonation of the metal icon.
