What’s the chemical formula for a red flame?
To create colored flame with red color safely, we can use lithium chloride. Lithium chloride belongs to salt compound with chemical formula LiCl. Even though original flame has orange-ish color, but the natural one has unstable color and less vibrant color. Therefore, to create red color, we can use lithium chloride.
How does calcium sulfate form in the water?
Calcium sulfate (CaSO 4) is one of several sulfate scales and is also called gypsum. Like CaCO 3, it can form either as a result of mixing dissimilar waters or naturally as a result of changes in temperature and pressure as the water travels from the subsurface to the surface treating facility.
What kind of flame does calcium carbonate produce?
Trish Gant / Getty Images. Calcium salts produce an orange flame. However, the color may be muted, so it can be hard to distinguish between the yellow of sodium or gold of iron.
