Which relation is correct for depression in the freezing point?
Answer and explanation
Correct answer: \(\Delta T_f = iK_fm\)
The depression in freezing point is given by \(\Delta T_f = iK_fm\). In this expression, \(i\) is the van’t Hoff factor, \(K_f\) is the cryoscopic constant of the solvent, and \(m\) is the molality of the solution. The symbol \(f\) identifies freezing-point depression. Option B is the corresponding formula for elevation in boiling point, while C and D describe osmotic pressure and the ideal-gas equation.
