Detailed explanation-1: -When exhaled air is blown into a test tube containing lime water, it is converted into limestone. Limewater becomes milky in the presence of carbon dioxide.
Detailed explanation-2: -When we breathe in air it contains oxygen reaches the lungs. There the gaseous exchange takes place. The air which we breathe out contains carbon dioxide. Therefore the air which we blow contains carbon dioxide reacts with the lime water and calcium carbonate is formed, which turns the lime water milky.
Detailed explanation-3: -Take a straw and a beaker. Fill the beaker with lime water. Blow air from the mouth using the straw into the beaker. The lime water present in the beaker will turn milky.
Detailed explanation-4: -Carbon dioxide turns lime water milky. This is due to the formation of calcium carbonate when carbon dioxide combines with calcium hydroxide (limewater). Was this answer helpful?
Detailed explanation-5: -Limewater as Indicator of Carbon Dioxide Gas. Description: Carbon dioxide gas from a cylinder is bubbled through limewater and calcium carbonate solid is formed causing the limewater to become cloudy.
