Calculate the van't Hoff factor of a centimolar solution of potassium ferrocyanide if it is 60 % dissociated at 300 K.

Step-by-step solution

The chemical formula of potassium ferrocyanide is K₄[Fe(CN)₆] . The dissociation reaction is: K₄[Fe(CN)₆] 4K^+ + [Fe(CN)₆]⁴⁻ The number of ions produced per formula unit, n = 5 . The degree of dissociation, = 60 % = 0.60 . The van't Hoff factor i is given by: i = 1 + (n - 1) Substituting the values: i = 1 + (5 - 1) 0.60 i = 1 + 4 0.60 i = 1 + 2.4 = 3.4 Answer: 3.4
