The flame test identifies ions by changing the flame color. This kit contains two solutions with a common cation: potassium.In this way, the student determines the ion, positive or negative, of the mineral salts responsible for the flame color change. For results visible to all, it is best to carry out the experiments with a high flame temperature to obtain a blue flame.The choice of salt minerals and concentrations involved have been optimized to reduce the pollutants and encourage classroom use.
- 7 flacons vaporisateurs 125 mL contenant les ions : K+ (contenu dans deux flacons) , Cu2+, Ca2+, Fe2+, Na+, Mg2+.
