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.
