Answer to Question #185648 in General Chemistry for Joshua

Question

Grace need to prepare a sulfuric acid solution using acid and distilled water. However, there is no distilled water left on the laboratory. Marie suggested to use the running water from the faucet, but Grace declined. Grace insisted that tap water should not be used in preparing solutions. Explain the basis of Grace's claims.

Answer 1

The water in the tap is not purified. The majority of municipal tap water contains chlorine. Chlorine is a chemical that is used to destroy bacteria in water. Some minerals, such as fluoride, which reduces tooth decay, can be deliberately dissolved in public drinking water.
