How to conduct a flame test

ions produce different flame colours when they are heated strongly. This is the basis of flame tests. To carry out a flame test: dip a clean wire loop into a solid. FLAME TESTS. 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. Here's how to perform a flame test and how to interpret the colors you see. You can use a flame test to identify a metal or ionic salt.

limitations of flame test

You can use a flame test to help identify the composition of a sample. Here's how to perform the flame test and analyze the results. Wear chemical splash approved goggles. Wear a chemical apron.
