- When salt dissolves in water, equal portions of this mixture contain the same quantities of sold and liquid. Such mixture is said to be
- uniform
- In a solution, the dissolved substances is called
- solute
- The liquid referred to as the \"univeral solvent\" is
- water
- A beam of light can be used to see
- dust in the air
- The particles in a solution
- are molecular in size
- When purple-colored potassium permaganate is dissolved in water, the solution formed
- becomes purple
- An example of a solution that is affected by changed in pressure is
- carbon dioxide in water
- Weak solutions are said to be
- dilute
- A solution to which more solute can be added at the same temperature is said to be
- unsaturated
- In general, when a hot substance, to which excess solute is added,cools,
- the excess solute settles to the botom of the container
- When the temperature of a liquid is raised, its ability to dissolve a solid solute
- increases
- When a solution of carbon dioxide in water is heated
- carbon dioxide leaves the solution
- An increase in pressure on a sodium in pressure on a sodium chloride solution
- has no effect
- When the pressure on a gas increases, the solubility of the gas in a liquid
- increases
- The best method to use to recover both the solute and solvent of a liquid solution is
- distillation
- Distiled water
- is chemically pure
- Fractional distillation can be used to obtain
- gasoline
- The process of chromatography is based on the principal of
- adsorption
