Would a dilute or concentrated sodium fluoride solution have a higher boiling point? explain.

concentrated sodium fluoride solution will have a higher boiling point

Explanation:

Colligative properties are properties that depend on the number of particles present. That is, the more the number of particles present, the greater the effect. Colligative properties include; melting point, boiling point and osmotic pressure.

Since the boiling point of a solution is a coligative property, it increases with increasing number of particles. There are definitely more particles in a concentrated than a dilute solution hence a concentrated solution will have a higher boiling point than a dilute solution.

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
