Question:medium

0.01 M solution of KCl and CaCl\(_2\) are prepared in water. The freezing point of KCl is found to be \(-2^{\circ}C\). What is the freezing point of CaCl\(_2\) (assumed to be completely ionised)?

Show Hint

\(\Delta T_f = i K_f m\). Van't Hoff factor \(i\) = number of ions per formula unit.
