Mixture

Two or more materials stirred together.

Solution

A special mixture formed when a solid materials dissloves in a liquid; It is transparent. It has two parts: the solute/solid part and the solvent/liquid part and can be separated by evaporation.

Dissolving

A process in whic one material (solid) spreads out evenly into another material (liqid), so that the first material seems to disappear.

Evaporation

Cuses liquid to dry up; the liquid turns into gas and disperses into the air , leaving any dissolved solid material behind.

solute

The solid part of a solution.

solvent

The liquid part of a solution.

Saturated solution

When a solute dissolves in a solvent until no more will dissolve.

Solubility

How well a substans dissolvese in a solvent,,such as the solubility of slat in water - 4spoons vs citric acid -11spoons that has a higher solubility.

concentratrated

An amount of material dissloved in a certain amount fo liquid; the higher amount of solute the her level of concentrtion.

Dilute

To make a solution less concentrated usually by adding more sovent.

Precipitate

A solid material that as a product of a reation.

Reactant

When two chemicals react when they are mixed, the chemicals are called reactants.

Fact:

When a solution evaporates, the dissolved solid material is behind.

Fact:

Salt (or any solute) will dissolve in the water untilmit reaches saturation. No more slat will dissolve once saturation is reached.

Fact:

As the amount of soute in a solution increases, the concentration also goes up.

Fact:when equal amounts of two solution - for example, each solution is 100ml - are compared on a balance/scale, the heavier one is more concentrated.
