The freezing point of a 1.324 m solution, prepared by dissolving biphenyl into naphthalene, is 71.12 ° C.
A solution is prepared by dissolving biphenyl into naphthalene. We can calculate the freezing point depression (ΔT) for naphthalene using the following expression.
[tex]\Delta T = i \times Kf \times m = 1 \times 6.90 \°C/m \times 1.324m = 9.14 \°C[/tex]
where,
The normal freezing point of naphthalene is 80.26 °C. The freezing point of the solution is:
[tex]T = 80.26 \° C - 9.14 \° C = 71.12 \° C[/tex]
