Video transcript

Barium sulfate (BaSO4) is an insoluble salt. This means it doesn't dissolve in water, making it useful in medical imaging as a contrast agent for X-rays. Insoluble salts like barium sulfate are crucial in various industries due to their unique properties.

Questions and answers

  1. What makes barium sulfate an insoluble salt?

    Barium sulfate is insoluble because its ionic compounds form a tightly bound lattice structure that does not break down easily in water, preventing it from dissolving.

  2. Why is barium sulfate used in medical imaging?

    Due to its insolubility and opacity to X-rays, barium sulfate serves as a contrast agent in X-ray imaging to highlight certain areas of the body clearly.

  3. Are all sulfates insoluble salts?

    No, while some sulfates like barium sulfate are insoluble, many sulfates such as sodium sulfate are soluble in water.
