Given the freezing point of the solution of ionic solid in water, the possible molecular formula of the ionic compound that cause the given depression in freezing point when mass of the compound is tripled has to be determined from one of the following - M X , MX 2 or MX 3 where M is metal cation and X is an anion with charge − 1. Concept Introduction: Freezing point of a liquid substance is defined as the temperature at which the liquid becomes and solid and both the phases remain in equilibrium. Depression in freezing point of a solvent due to the addition of non-volatile solute can be determined by the formula, Δ T f = i × K f × m . Where, Δ T f = depression in freezing point K f = depression in freezing point constant m = molality of the solution; i = Van't Hoff factor

Concept Introduction:
Freezing point of a liquid substance is defined as the temperature at which the liquid becomes and solid and both the phases remain in equilibrium.
Depression in freezing point of a solvent due to the addition of non-volatile solute can be determined by the formula,
ΔTf = i×Kf×m.
Where,
ΔTf = depression in freezing pointKf = depression in freezing point constantm = molality of the solution; i = Van't Hoff factor
