How does washing soda help in softening hard water?

Answer and explanation

Correct answer: It helps remove calcium and magnesium ions

Hard water contains dissolved calcium and magnesium salts. Washing soda, sodium carbonate (Na₂CO₃), reacts with these ions and can precipitate them as insoluble carbonates, such as calcium carbonate and magnesium carbonate. Removing these ions reduces hardness, so soap can form lather more easily. It does not acidify water, convert water into hydrogen gas, or destroy soap. Therefore, option A is correct.
