Flame Test Chemical Kit With Five Chemicals For Sale
Cupric Sulphate, Potassium Chloride, Cupric Chloride, Strontium Chloride, Sodium Carbonate
Our flame test kit is a low-cost approach to use the colour of the flame when the chemical sample is placed inside it to visually identify and count the number of a metal or metalloid ion.
Use a nichrome wire loop similar to an inoculating loop to do the test by soaking it in pure alcohol (not included in this kit), then pick up a small amount of one of the chemicals. Put the chemical-filled loop in the burner’s hottest area of flame. When the chemical sample burns, pay attention to the hue of the flame.
In order to prevent dust or other contaminants from obscuring the real colour of the test sample flame, the wire should be thoroughly cleaned by immersing it in alcohol between samples. You can also use spatulas made of stainless steel.
HEALTH: Put on a lab chemical apron and splash goggles. This activity should be done by teenagers under adult supervision.
compounds STORAGE: A few of these compounds are hygroscopic, which means they will take in moisture from the environment. When not in use, keep the cap tightly closed. If a chemical becomes slushy, remove the extra moisture by storing it in a sealed container with a desiccant, like a packet of silica gel.
Another option is to make a tiny pile of one of the chemicals and moisten it with flammable alcohol to show the different flame colours. The chemical will burn when the alcohol is ignited, producing its distinctive flame colour.
