## Introductory Chemistry (5th Edition)

The popular statement is like dissolves like. That is, a polar compound dissolves in the polar solvent while a nonpolar compound dissolves in the nonpolar solvent. When like dissolves in like, the mixture formed is homogenous. a. Water is polar, and $CCl_{4}$ is nonpolar, Hence they don't form a homogenous solution. b. Bromine and $CCl_{4}$ both are nonpolar. Hence they form a homogeneous mixture. c. Water and ethyl alcohol both are polar, hence when mixed they form a homogeneous solution.
