Flame tests using metal salts | Resource | RSC Eduion
Record the metal salt solution and the flame colour. Repeat steps 2 to 4 for each of the other metal salt solutions you have been provided with. Theory: Calcium ethanoate is a very hygroscopic solid. This means it absorbs and coordinates with water very easily.
Flame Tests - Chemistry LibreTexts
Flame tests are used to identify the presence of a relatively small nuer of metal ions in a compound. Not all metal ions give flame colors. For Group 1 compounds, flame tests are usually by far the easiest way of identifying which metal you have got.
