Heat of solution for NaCl is ?
Correct answer: B. Low
- A. High
- B. Low
- C. Zero
- D. One
Explanation
The heat of the solution for NaCl is low. When NaCl dissolves in water then the enthalpy of the solution decreases and the reaction of NaCl with water is endothermic so, heat has to be added to the solution. Thus NaCl solution possesses low heat than normal water.The heat of the solution for NaCl is low.

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
