volumetric analysis

a type of analysis that involves reacting together volumes of solutions

concentration of a solution

the amount of solute that is dissolved in a given amount of solution

percentage weight per weight

number of grams per 100 grams of solution

percentage weight per volume

number of grams per 100 cm3 of solution

percentage volume per volume

number of cm3 per 100cm3 of solution

parts per million

number of milligrams per litre

molarity

the number of moles of solute per litre of solution

mass of one mole

the atomic/molecular mass expressed in grams

a molar solution

one mole of solute dissolved in one litre of solution

number of moles eqn

volume x molarity/1000

molarity eqn

no.of moles/volume x1000

primary standard

pure,stable, soluble solid that can be weighed out and dissolved in water to give a solution of accurately known concentration

standard solution

a solution of precisely known concentration

titration

laboratory procedure where a measured volume of one solution is added to a known volume of another solution until the reaction is complete

solving volumetric problems

1. no. of moles

2. ratio

3. molarity

water of crystallisation

water that makes up part of the crystal structure of the compound, the compound is said to be hydrated.
