Niter

Niter (/'naɪtər/), also known as saltpeter or potassium nitrate, is a chemical compound with the chemical formula KNO3. It is a strong oxidizer that can be found in certain types of soil and in various plants.

Etymology

The term "niter" comes from the Greek word "nitron", which itself was borrowed from the Ancient Egyptian word "netjry", meaning "natron". Natron is a naturally occurring mixture of sodium carbonate decahydrate and about 17% sodium bicarbonate along with small quantities of sodium chloride and sodium sulfate.
