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
