Question

For which among the following equimolar aqueous solutions Van't Hoff factor has the lowest value?

Options

• Aluminium chloride

• Potassium sulphate 

• Ammonium chloride

• Urea

Answer 1

Urea

Explanation:

Number of total ions present in the solution is known as Van't Hoff factor. Because urea is a molecular solid, it does not associate or dissociate, giving it the lowest van 't Hoff factor (i) value.
