Which among the following salts, solubility decreases with increase in temperature?

Options

  1. AN a 2 S O 4
  2. BN a B r
  3. CN a C l
  4. DK C I

Correct answer

A. N a 2 S O 4

Step-by-step solution

For N a 2 S O 4 salt, solubility decreases with increases in temperature because reaction of N a 2 S O 4 with water is an exothermic reaction, i.e. Δ s o l H < 0 . As a result solubility decreases. N a C l and K C I , the dissolution process is endothermic.
