Question

b) Ranjana has two unknown solutions: X, and Y. She performed certain tests with
indicators and observed the following:
(1) Solution X
phenolphthalein remains colourless.
(ii) Solution Y + sugar solution
Phenolphthalein turns pink.
fit) Solution X + Solution Y
Phenolphthalein remains colourless.
Identify the nature of the solutions X and Y. Give one property for each of them.​

Answer 1

Answer:

Solution X is an acidic solution.

• An acid gives H+ ion(or hydronium ion) as the only positive ion when dissolved in water or in aqueous solution.
• it also turns blue litmus red.

Solution Y is a basic solution.

• A base gives OH- ion (or hydroxyl ion) as the only negative ions when dissolved in water on in aqueous solution.
• it also turns red litmus blue.
