Answer:

Curd contains lactic acid while the sour substances contain citric acid. When these substances are kept in a brass or a copper vessel, the acid present in the substance reacts with the metal, to form a compound that is poisonous and can affect our health badly.

So option a is correct answer

Have a nice day!

Of the following statements B. While diluting acids, water should be added to acids in small amounts is false.

  • While diluting acids, water should not be added to acids because mixing concentrated acid and water is highly exothermic, that is the amount of heat generation is very high. This amount of heat can splash on the face and cause injuries.
  • Adding acid to water can absorb most of the heat and it won't splatter or explode. That is why it's recommended to add acid to water. Hence, state B is a false statement.
