Overview Potassium sulfide is an inorganic salt that is not found as an isolated compound in nature. It always found as a mixture with potassium hydrosulfide. It is a colorless crystal with a typical sulfur smell. Potassium sulfide can be prepared through the reaction of pure carbon with potassium sulfate at high temperatures. Potassium sulfide … Read more
Gas chromatography is the most widely used form of chromatography in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. Gas chromatography is used to separate complex mixtures of different molecules based on their physical properties such as polarity and boiling point. The other uses of gas chromatography include: Testing purity … Read more
Overview Polyphosphoric acid (H3PO4) is a colorless, odorless and highly viscous liquid compound with strong hydroscopic properties. It is a mixture of linear phosphoric acids and orthophosphoric acid. Phosphoric acids with less than 95% H3PO4 (68% P2O5) contain the simple orthophosphoric acid. However, at higher concentrations, the acid consists of a mixture of ortho, pyro, … Read more
What Is Formic Acid? Formic acid or methanoic acid is the simplest member of the carboxylic/alkanoic acid series. It occurs naturally in stinging nettle leaves and insect sings such as stingless bees, wasps, puss moth caterpillar and some ants. It can be synthetically in industries or laboratories through processes such as: hydrolyzing formamide, hydrogenation of … Read more
What Are Halogens? Halogen is a term that was derived from the Greek word ‘halo’ which means salt and ‘gen’ meaning producer. The term halogen therefore means salt producer. This is because they produce a wide range of salts when they react with metals. The name halogen was first proposed by a German chemist by … Read more
A laboratory is a special room or place that is equipped to facilitate scientific experiments, observations and for teaching science. Laboratory apparatus refers to the various tools, equipment, and instruments used in scientific research, experimentation, and analysis within a laboratory setting. These tools are essential for conducting experiments, measuring and analyzing data, and ensuring the … Read more
What Is An Electrode? The term electrode was derived from two Greek words; “electron” which means amber and “hodos” meaning a way. Electrode therefore, refers to an electricity conducting material that connects nonmetallic parts of a circuit such as electrolytes, air, semiconductors and a vacuum. It is simply the point where the current enters and … Read more
