Study Notes
Gravimetric Analysis
- Gravimetric analysis is based on determining the mass of a pure compound to which the analyte is chemically related.
- It is a type of analysis based on determining the weight of a substance in a sample from the weight of a chemically equivalent amount of some other substance.
Loss on Ignition
- The purpose of Loss on Ignition is to determine the amount of volatile matter in a sample.
- It is different from Loss on Drying in that it involves heating the sample to a higher temperature to remove any volatile matter.
Loss on Drying
- The temperature range used in Loss on Drying is typically 100-150°C.
- The purpose of Loss on Drying is to determine the amount of moisture in a sample.
Particulate Gravimetry
- The first step in Particulate Gravimetry is to separate the particles from the sample.
- Particulate Gravimetry can be used to determine the amount of a specific substance in a sample, such as the amount of a particular metal or compound.
- It is used in pharmaceutical analysis to determine the purity of a substance.
Pharmaceutical Analysis
- The purpose of Gravimetric Analysis in pharmaceutical analysis is to determine the purity of a substance.
