Question

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

• A. Antacid acting on acid in stomach
• B. Treatment of acidic soil by powdered lime
• C. Usage of conditioner after shampooing your hair
• D. All of them

Answer 1

The correct option is D All of them

Antacids consist of bases, carbonates and bicarbonates like calcium carbonate, aluminium hydroxide, sodium bicarbonate. 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 in the skin.

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