Nitrogen is a chemical element with the symbol N, the atomic number 7, and the mass 14.007u. Nitrogen is abundant on Earth, accounting for 78 percent of the atmosphere’s gas; the rest is oxygen gas, accounting for roughly 21% of the atmosphere’s gas, with traces of other gases. Nitrogen exists in the atmosphere as the […]

Carbon, oxygen, nitrogen, phosphorus, and sulphur are only a few of the essential elements that soil contains. When it comes to these elements, nitrogen is believed to be one of the most vital. All of these nutrients are taken by plants, although not directly by the plants themselves. Taking nitrogen as an example, plants are

Chromatography is a technique used for the separation, purification, and testing of different types of substances. The term “chromatography” is derived from the Greek words chroma, which means “color,” and graphein, which means “to write,” as in “to write in color.” We apply the mixture to be separated on a stationary phase (solid or liquid),

The definition of a buffer in chemistry is a solution that can resist pH change when an acid or base is added. It’s made up of a weak acid and its conjugate base, or the other way around. In acid-base chemistry, a buffer is a very useful solution. When a strong acid or base is

Buffers are substances or mixes of substances that withstand changes in pH when modest amounts of acid or alkali are added to the solution. A weak base and its conjugate acid, or a weak acid combination and its conjugate base, make up a buffer solution.  It prevents pH shifts or minor alterations caused by little

Nitric acid is a colorless, fuming, and highly corrosive liquid that is a common laboratory reagent and an important industrial chemical for the manufacture of fertilizers and explosives. It has a boiling point of 84.1 degrees Celsius and freezes at -41.55 degrees Celsius. It forms a kind of white solid after that. Its chemical name

To the early alchemist, the development of nitric acid and its use was mainly known. In 1648, German chemist, Johann Rudolf Glauber ascribed a common laboratory process that was used for many years, the laboratory mainly consisted of heating potassium nitrate along with concentrated sulfuric acid.  Antoine-Laurent Lavoisier, a chemist of 1776 showed that the
