Considering acetic acid dissociates in water, its dissociation constant is $6.25 \times 10^{-5}$. If $5 \mathrm{~mL}$ of acetic acid is dissolved in $1$ litre water, the solution will freeze at $-\mathrm{x} \times 10^{-2}{ }^{\circ} \mathrm{C}$, provided pure water freezes at $0^{\circ} \mathrm{C}$.
