A 0.001 molal solution of a complex [MA8] in water has the freezing point of 0.005580C. Assuming 100% ionization of the complex salt and Kf for H2O = 1.86 ºC m 1 , write the correct representation for the complex.

Dear student
Since we know that,
\DeltaTf = i*Kf*m
0.005580 = i* 1.86 *0.001
i = 3
This means the complex is releasing 3 ions in aqueous solution which makes the complex as
[MA6]A2
