SOLUTIONS

Liquids with two or more components that from a homogeneous mixture

SOLUTIONS

SOLVENT

SOLUTE

EXAMPLES

Metal alloy

Brass

Concentration:

C = n/v

ppm = mass of component/ total mass of solution X 10^6

Dilution:

Reduces concentration of solute

Solution + Solvent

Number of moles remains constant

n = constant

Volumetric analysis:

Method of calculating concentration of an unknown solution based on another

Technique

Tools

Titration:

Method to determine volume of reactants

Pipette

Conical flask

Burette

Standard solutions: Known concentrations

EXAMPLE

Volumetric flask

Equivalence point:

Point of total reaction

Indicator:

Little string of paper that is added to the solution to mark changes in PH

END POINT:

Time of finalization of the reaction of two solutions
