. Which of the following statements about solutions is false? a. All solutions are mixtures.
b. All solutions are homogeneous.
c. All solutions contain two or more compounds.
d. All solutions contain at least two substances.

The statement false about solution has been that all solutions are mixtures. Thus, option A is correct.

The solution can be defined as the dissolution of two or more substances. Thus, all solutions are been considered as dissolution of the solute and solvent molecules.

The solution has generally been the homogenous mixture as there has been the complete dissolution of the substances. However, the mixture can be defined as the combination and not the complete dissolution of the substances.

Thus, all solutions have not been considered as mixtures. Thus, option A is correct.
