2020/8/16· This page describes how to do a flame test for a range of metal ions, and briefly describes how the flame colour arises. 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 colours. For Group 1 compounds, flame tests
THE SCIENCE OF SOAPS AND DETERGENTS
Soaps, will react with metal ions in the water and can form insoluble precipitates. The precipitates can be seen in the soapy water and are referred to as “soap scum”. This soap scum can form deposits on clothes causing them to be gray or yellow in color.

How Flame Test Colors Are Produced - ThoughtCo
2020/2/21· Calcium The noble metals gold, silver, platinum, palladium, and some other elements do not produce a characteristic flame test color. There are several possible explanations for this, one being that the thermal energy isn''t sufficient to excite the electrons of these elements enough to release energy in the visible range.
