Question

Choose the correct statement:

Statement I: Hard water is ideal for laundering clothes as it enhances the effectiveness of detergents, resulting in better cleaning.

Statement II: Soft water is more efficient for laundering because it allows detergents to lather easily and effectively removes dirt from fabrics.

Options

• Statement I is true, and Statement II is false.

• Statement I is false, and Statement II is true.

• Both Statements I and II are true.

• Both Statements I and II are false.

Answer 1

Statement I is false, and Statement II is true.

Explanation:

Soft water is highly efficient for laundering because it lacks high concentrations of calcium and magnesium ions, allowing soaps and detergents to dissolve and lather easily, effectively removing dirt. In contrast, hard water reacts with detergents to form an insoluble substance called scum or curd, which reduces cleaning efficiency, wastes detergent, and leaves a grey residue on clothes.
