1g of tartaric acid is dissolved in 100cc of water. Take a few cc of the acidic solution in test-tube and mix few drops of coloured C₂₀H₁₄O₄ (phph) solution (prepared in basic medium) into it.
1. The colour of the solution instantly changes pink
2. remains colourless as the colour of the added drops disappears
3. the colour diffuses through the solution and finally disappears
4. the colour diffuses through the solution and finally the entire solution acquires a faint pink colour?

Explanation:


The given acidic solution contains tartaric acid which is a weak acid. When a few drops of coloured C₂₀H₁₄O₄ solution (prepared in basic medium) is added to it, the following reaction takes place:

C₂₀H₁₄O₄ + H⁺ → C₂₀H₁₄O₄H

The resulting product C₂₀H₁₄O₄H is acidic in nature and hence changes the colour of the solution. The observation depends on the concentration of the solution and the amount of C₂₀H₁₄O₄ added.

Options:

  • Option 1: The colour of the solution instantly changes pink

  • Option 2: remains colourless as the colour of the added drops disappears

  • Option 3: the colour diffuses through the solution and finally disappears

  • Option 4: the colour diffuses through the solution and finally the entire solution acquires a faint pink colour



Answer:


The correct option is Option 4: the colour diffuses through the solution and finally the entire solution acquires a faint pink colour. When the coloured solution is added to the acidic solution, the colour of the added drops diffuses through the solution and finally the entire solution acquires a faint pink colour due to the formation of the acidic product C₂₀H₁₄O₄H. This happens because tartaric acid is a weak acid and does not dissociate completely in water. Hence, the resulting solution is still acidic and reacts with the coloured solution to form the product.
