WebThis test has to be done in solution. If you start from a solid, it must first be dissolved in pure water. The solution is acidified by adding dilute nitric acid. (Remember: silver nitrate + dilute nitric acid.) The nitric acid reacts with, and removes, other ions that might also give a confusing precipitate with silver nitrate. WebA common test to distinguish group 1 and group 2 ions is the flame test, where the metal compound or its solution is heated in a roaring blue Bunsen flame. The resulting coloured flame can be used to identify the cation present. A number of experimental techniques can be used as shown in the videos below.
