How can temporary hardness of water be removed through heating?

How can temporary hardness of water be removed through heating?

Options

  1. AHeating causes calcium and magnesium to evaporate.
  2. BHeating converts calcium and magnesium hydrogen carbonates into insoluble compounds.
  3. CHeating breaks down calcium and magnesium into their respective ions.
  4. DHeating increases the solubility of calcium and magnesium compounds.

Correct answer

B. Heating converts calcium and magnesium hydrogen carbonates into insoluble compounds.

Step-by-step solution

Heating water with temporary hardness causes calcium and magnesium hydrogen carbonates to convert into insoluble compounds like calcium carbonate and magnesium hydroxide, which can then be removed by filtration.
