Electrogravimetric determination of copper Principle Electrogravimetry is an important analytical method for the quantitative determination or separation of species in solution. The technique involves the quantitative electrolytic deposition of an element, usually a metal, on a suitable electrode in weighable form. Benefits - High quality platinum electrode for precise results
- Optimized test procedure by heating
Tasks Perform an accurate electrogravimetric determination of the amount of copper in a given sample solution. Learning objectives - Quantitative analysis
- Gravimetry
- Electrolysis
- Overpotential
- Electrode polarisation
Necessary accessories - Analytical balance 120g/0.1mg
