When NaCl (sodium chloride) is added to H₂O (water),

The solid salt dissolves and dissociates into its constituent ions, sodium (Na⁺) and chloride (Cl⁻),

The equation for this process is: 

NaCl(s) + H₂O(l) → Na⁺(aq) + Cl⁻(aq) 

Explanation

The boiling point of water decreases at higher altitudes due to Low atmospheric pressure

The boiling point of water increases with increased atmospheric pressure

The boiling point of water decreases with decreased atmospheric pressure
