Uses of acids and bases

Industries emit several gases and waste products into the environment leading to environmental pollution. Some of

these gases dissolve in rain water to form acid rain. This

rain reacts with stone work, iron roofs and other metallic surfaces causing damage. This effect is called corrosion.

When these acidic gases in the atmosphere are inhaled they cause respiratory disorders. Soil may become acidic due to

leaching and water logg. Such soil is unsuitable for the growth of many plants. Applications of Acids and Bases
