Explain why hydrogen peroxide is stored in coloured plastic bottles.

Transition metal ions are generally coloured. Why?

Assertion : The boiling point of chloroform-acetone solution is larger than expected from ideal behaviour. Reason : The forces of attraction between unlike molecules are stronger than those between like molecules in the solution. This results in lower vapour pressure as compared to an ideal solution which is responsible for the higher boiling point.

When we pass carbon dioxide gas through a green coloured solution of potassium manganate, the colour of solution changes to purple and a brown coloured solid gets precipitated. The green colour of potassium manganate solution also becomes purple when it is subjected to electrolysis using iron electrodes. The change of colour from green to purple is due to
