Heat of solution for NaCI is:
Correct answer: B. Low
- A. High
- B. Low
- C. Zero
- D. One
Explanation
Based on the usual behavior of heat of solution for common ionic compounds like NaCl, the correct option is B) Low. When NaCl dissolves in water, the heat of solution is relatively low, meaning that the dissolution process does not involve a significant amount of heat exchange.

About Thermochemistry and Energetics of Chemical Reactions
Thermochemistry measures energy changes in chemical reactions and distinguishes exothermic from endothermic processes. Work covers systems, surroundings and state functions, internal energy, the first law of thermodynamics, enthalpy and Hess's law, including the sign conventions used when heat enters or leaves a system.
