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 |
