when we add salt to water, the boiling temperature of water increases. a true b false
Answer
# Brief Explanations:
When salt (a non - volatile solute) is added to water, it lowers the vapor pressure of the solution. According to the boiling point elevation formula $\Delta T_b = iK_bm$, where $i$ is the van't Hoff factor (for $NaCl$, $i = 2$ as it dissociates into $Na^+$ and $Cl^-$ ions), $K_b$ is the ebullioscopic constant of the solvent (water), and $m$ is the molality of the solution. Since $\Delta T_b>0$, the boiling point of the solution (salt - water) is higher than that of pure water.

A. TRUE
