Watch this experiment in our practical video Identifying ions.
The method described in this experiment is intended for students to carry out and avoids the need for the use of concentrated hydrochloric acid. It also avoids the cost and contamination problems associated with the use of nichrome or platinum wires.
This practical is part of our Chemistry for non-specialists collection.
Worksheets, project-based learning tasks and contextualisation stories to develop a core understanding of analytical chemistry
