Question

What happens to the boiling point of water when salt is dissolved in it?

Answer 1

When dissolving salt in water you raise the boiling point, while the freezing point is being lowered. There are colligative properties and depend only on the number of particles in the solution, not what kind they are.
All the information regarding colligative properties can be found in the chemical potential:
\[\Large \mu_A=\mu_A^{\circ}+RT \ln \left( x_A \right)\]
The reduction of the chemical potential in a phase change temperature due to solvent can be evaluated to:
\[\Large \Delta T_b=K_b \times b\]
\[\Large \Delta T_f=K_f \times b\]
