What are some examples of when a mixture can always be a solution?

All homogeneous mixtures

Explanation:

"All solutions are mixtures, but not all mixtures are solutions."

A mixture is a solution only when it is homogeneous; i.e. the components are dispersed evenly throughout.

Some examples of solutions are

• dissolved $\text{NaCl}$ in water

• sea water (various dissolved ions)

• bright blue ${\text{CuCl}}_{2}$ solution (dissolved ${\text{Cu}}^{2 +}$ and ${\text{Cl}}^{-}$ ions)

• vinegar (contains acetic acid, $\text{CH"_3"COOH}$)

• hydrochloric acid (concentrated ${\text{H}}^{+}$ and ${\text{Cl}}^{-}$ ions)

• coffee (dissolved sugar molecules)

• regular tap and bottled water! (there are, albeit in small quantities, some dissolved ions in tap water and bottled water (check the information label); this allows for the water to conduct a slight current, which is why you were probably told not to bring electrical devices in the bathtub!)
