Explain any three neutralization reactions related to daily life situations
Answers
Answer:
Indigestion: Sometimes, the stomach produces too much hydrochloric acid, called hyperacidity, which causes indigestion. The acid is neutralised by taking a tablet (antacids) containing calcium carbonate, aluminium or sodium hydrogencarbonate.
Ant sting: When you are stung by an ant, the burning sensation on your skin is caused by methanoic acid. You can neutralise the acid by rubbing a dock leaf on the wound. As you press the dock leaf against the wound, a base in the leaf juices reacts with the acid in the sting and neutralises it so that the burning sensation stops.
Vinegar is used to cure wasp stings that are alkaline in nature. Baking powder is used to cure bee stings and ant bites that are acidic in nature. Toothpaste contains bases that neutralise the acid produced by bacteria in our mouth. Baking powder is usually used to help the cakes rise.
