  4. Asked: September 21, 2021In: Class 10 Science

    Explain why soap does not give lather with hard water easily.

    Best Answer
    Ikshita Bhatti
    Added an answer on September 21, 2021 at 6:08 am

    Hard water contains calcium ions and magnesium ions. Soap does not give lather with hard water easily because it reacts with the calcium and magnesium ions present in hard water to form insoluble calcium and magnesium salts.
