The two solutions that have similar solubilities at 40°C will be Na₂HAsO₄ and Na₂SO₄.

What is solubity ?

It is the ability of a solute to be dissolved, especially in water.

As the temperature increases the solubility of the gas generally decreases"

According to given information and graph attached as reference ;

  • Solubility of NaCl (sodium chloride) at 40°C is 36.3 grams.
  • Solubility of Na₂SO₄ (sodium sulfate) at 40°C is 48.8 grams.
  • Solubility of Na₂HAsO₄ (sodium arsenate dibasic) at 40°C is 48.9  
    grams.
  • Solubility of Ba(NO₃)₂ (barium nitrate) at 40°C is 14.1 grams.
  • Solubility of Ce₂(SO₄)₃·9H₂O (ceasium sulfate nonahydrate) at 40°C is 6.2 grams.
