Question

Which among the following is not an example of neutralisation reactions in everyday life?

• A. Antacids acting on excess stomach acid
• B. Treatment of acidic soil with powdered lime
• C. Usage of conditioner after shampooing your hair
• D. Corrosion of metal in presence of moisture

Answer 1

The correct option is D Corrosion of metal in presence of moisture

Antacids consist of mild bases like magnesium hydroxide. These reacts with the hydrochloric acid produced in the stomach neutralising it and aids in proper digestion.

Use of slaked lime in acidic soil helps to neutralise the soil acidity and make the soil suitable for crops.

Shampoos are basic in nature and conditioners are acidic. Use of conditioners after shampooing helps to neutralise the effect of shampoo on the skin.

Corrosion is the layer by layer gradual oxidation of metals. It is not a neutralisation reaction.
