Most of the liquids we see around us are solutions or mixtures having more than one substance in it. For example, the water you get in a tap or a hand pump, is not pure water, but is a solution containing several salts and some gases. Yet we don’t see that water as a salt solution. But if the water has a lot of salt in it like sea water we call it salty water or salt solution. Thus in our common life, the amount of dissolved substance makes us label the liquid as a pure substance or a solution.
