Study Notes
- Ceric sulfate and sodium oxalate undergo direct cerimetry.
- Sulfuric acid is used to stabilize ceric sulfate, and acidic conditions prevent hydrolysis.
- Potentiometric method and self-indicators can be used in cerimetry.
- Sodium bicarbonate is used in direct acidimetry.
- Sodium thiosulfate and potassium dichromate undergo redox titration.
- Blank tests are important in titration.
- Zinc sulfate and edetate disodium undergo direct complexometric titration.
- Dithizone is used as an indicator in complexometric titration.
- Zinc absence results in green color.
- Solubility of substances in alcohol is important in titration.
