Molar concentration/molarity

Parts per million/billion

Concentration

Standard solution

Percent concentration

Dilutions

Stock solution

Dilutes

Changes the concentration

Electrolytes

Ph scale

Neutral

Basic

Acidic

Measures the degree to which a solution ionizes

Arrhenius Theory

Bases

Dissociation

Production of hydroxide ions

Acids

Ionization

Production of hydrogen ions

"Like dissolves like"

Ionic compounds dissolve in polar solvents

Non-polar solutes dissolve in non-polar solvents

Polar solutes dissolve in polar solvents

Intermolecular forces make it possible

It can interfere depending on the polarity

Homogenous mixture

Mixture with just one phase

Heterogenous mixture

It has two or more distinct phases

Solute

Solute that does not dissociate

E.g.: salt and sugar

Solvent

E.g.: water (water is polar)
