AH Chemistry - Stoichiometry
- Volumetric Analysis
- Dilution
- C1V1 = C2V2
- Standard Solution
- Primary standard
- High GFM
- Stable in air
- High purity
- Water soluble
- Dependent on writing BALANCED EQUATIONS
using the 2 triangles
- Gravimetric Analysis
- Conversion of a chemical to a product that can be
isolated and weighed
- Used if analyte is insoluble, where volumetric
analysis won't work
- E.g. a solid formed in a reaction
- Complexometric
- Metal ion concentrations calculated when forming
complexes
- Usually EDTA 1:1 ratio with metal ion
- Acid/base and redox
- As at National 5 and Higher
- Calculations can be completed by...
- Working out the number of
moles of given info
- Using mole ratio to work out number of moles of
unknown
- Calculate mass/concentration
