WebMay 8, 2016 · The decrease in freezing point ΔT f0 = T f0 – T f is known as depression in freezing point. For dilute solutions, the depression in freezing point (ΔT f) is directly proportional to the molal concentration of the solute in a solution (Molality). Thus, Where, m = molality i.e. the number of moles of solute dissolved in 1 kg of solvent. WebJan 16, 2024 · Freezing Point Depression In general (and as will be discussed in Chapter 8 in more detail) a liquid will freeze when μsolid ≤ μliquid As such, the freezing point of the solvent in a solution will be affected by anything that changes the chemical potential of … part time verticale festività
