Look at figure which shows solutions taken in test tubes A, B, C and D. What colour is expected when a piece of red litmus paper is dropped in each test tube? Nature of the solutions is given in the table for your help
|Test tube||Nature of Solution||Change in colour of red litmus|
|A (milk in water)||Neutral||No change|
|B (baking powder in water)||Basic||Turns blue|
|C (vinegar in water)||Acidic||No change|
|D (glucose in water)||Neutral||No change|
