Question

Which among the following is an example of neutralization reactions in everyday life?

• A. Burning of wood in presence of air
• B. Corrosion of metal in presence of moisture
• C. Treatment of acidic soil with powdered lime
• D. Antacids acting on excess stomach acid

Answer 1

Answer: (C), (D)

The correct options are
C Treatment of acidic soil with powdered lime
D Antacids acting on excess stomach acid

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