In which of the following salts, the solubility increases appreciably with increase in temperature?

Options

  1. AKBr
  2. BNaBr
  3. CNaCl
  4. DKCl

Correct answer

A. KBr

Step-by-step solution

The solubility of solid solute depends upon temperature. Variation of solubilities of some ionic solids with temperature - Generally, rise in temperature increase the solubility. This is due to expansion of holes or empty spaces in the liquid solvent. Generally, 10^ C rise in temperature, increase the solubility of solids two-fold. - Dissolution process may be endothermic or exothermic. - The solubility of the substances like NaBr , NaCl , KCl , etc. changes slightly with the increase in temperature. - The solubili
