What is the method which can be used to differentiate sulphuric acid and ethanoic acid?

One method to differentiate between sulphuric acid (H2SO4) and ethanoic acid (CH3COOH) is by using litmus paper. Sulphuric acid is a strong acid and will turn blue litmus paper red, while ethanoic acid is a weak acid and will also turn blue litmus paper red, but the color change may be less intense. Additionally, the two acids have different chemical formulas and properties.

How would you distinguish Sulphuric acid from Nitric acid and Hydrochloric acid by a chemical test?

To distinguish between Sulphuric acid, Nitric acid, and Hydrochloric acid, you can perform a simple red litmus test: Sulphuric acid turns blue litmus paper red, Nitric acid bleaches red litmus paper, and Hydrochloric acid does not affect the color of red litmus paper. This test is based on their acidic properties and reactions with litmus paper.


What happen when sulphuric acid added to red cabbage?

When sulfuric acid is added to red cabbage, the pH of the solution decreases due to the acidity of the acid. This results in a color change of the red cabbage indicator. The red cabbage changes color based on the pH of the solution it is in, with acidic solutions turning it red/pink and basic solutions turning it green/blue.
