mixture
a substance made by mixing 2 or more chemicals together.
solution
it is formed when a solvent is dissolved completely in a solvent to give a clear liquid.
solvent
the liquid in which another substance (solute) is dissolved.
solute
the susbtance that gets dissolved in a solvent.
solubility
the ability of one substance to dissolve in a solvent.
saturated solution
a solution that contains as much dissolved solute as possible at a specific temperature
unsaturated solution
a solution that has less than the maximum amount of solute being dissolved.
supersaturated solution
a solution that contains more than the maximum amount of solute that can normally be dissolved in the solvent at a specific temperature
suspension
a mixture with very small pieces of solid are spread through a liquid but do not dissolve; these solid particles will eventually settle to the bottom.
precipitate
a solid formed as a result of a chemical reaction by mixing two solutions together.
colloid
a mixture which is made up of small particles dispersed throughout another substance. The particles can't be filtered by a filter paper.
Tyndall effect
a beam of light that passes through a colloid or a suspension will be visible.
emulsion
a type of colloid mixture in which a liquid is dispersed evenly in another liquid.
immiscible
a condition in which 2 liquids can't be mixed together, eg. oil and water.
emulsifying agent
a chemical that can allow immiscible liquids to form an emulsion, eg. detergent, mustard and paprika.
diluted solution
a solution with very little solute dissolved in a large volume of solvent, eg. very little salts dissolved in the water.
concentrated solution
a solution with a lot of solute dissolved in a solvent,e g. undiluted cordial.
