Mixture

Mixture

Colloid

heterogenous, large molecules or particles, 1-1000nm, does not separate, does not filter, tyndall effect

Suspension

heterogenous, large particles, aggregates, > 1000nm, separates, filters, tyndall effect

Solution

 homogenous, ions, atoms, small particles, 0.1-1nm, does not separate, does not filter, no scattering

Solvent

the substance dissolved to make the solution

Solute

 the substance that dissolves the solute to make the solution

Concentration

the quantity of a solute that is contained in a particular quantity of solvent or solution

Calculating Concentration

M = n (solute) / L (solution

1. convert mass of solute to moles using molar mass

2. divide the moles by the volume of the solution, in L

Dilutions

M1v1 = M2V2
