When utensils are washed with hard water, they tend to lose their lustre.

• A. True
• B. False

Answer 1

The correct option is A True

When utensils are washed with hard water, they tend to lose their lustre. This is because, hard water may contain dissolved salts of calcium or magnesium ions. When this water is boiled, some insoluble deposits are formed on the inside surface of the utensils which gives the utensils a dull and dirty look.
