Uses of Hydrochloric acid |In Industry, Home and Daily life

uses of hydrochloric acid

Hydrochloric acid also called as muriatic acid is represented as HCl. This acid is a monobasic mineral acid which means every molecule releases only one hydrogen atom when it is dissolved in water, and it gets ionized.The hydrochloric acids uses include To make aqua regia To generate Hydrogen gas In manufacture of inorganic chemicals. In […]

Difference between Ion and Atom

Ions of sodium and chloride in water

The difference between ion and atom are given in the table below. But before that one needs to be clear of what is an atom and ion. Atom is the basic unit of matter. A group of atoms makes up matter. These atoms have a nucleus, with protons and neutrons in it. This nucleus is […]

What is sodium hydroxide? Its Synthesis, Reactions and Uses

Sodium hydroxide is a very commonly used laboratory chemical. Its physical characteristics are it is white in color, odorless, has a crystalline texture and is solid. Sodium hydroxide is a highly caustic and corrosive compound. It melts at 591K and the crystals of sodium hydroxide are deliquescent i.e. the crystals absorb moisture from the air […]

Mass Spectrometry Principle,Types, Instrumentation & Applications

Instrumentation of mass spectrometry

Mass Spectrometry is an analytical technique used to determine the mass and molecular structure of a compound. Unlike other spectroscopy techniques, here the electromagnetic radiation is not used for excitation of electrons. Further, there is also no phenomenon of electrons moving in between the ground state and excited state. The principle of mass spectrometry is […]

NMR Spectroscopy Principle, Instrument and Applications

NMR instrument

Nuclear magnetic resonance spectroscopy is one that studies the spin changes at the nuclear level. This spin change occurs when a radio frequency energy is absorbed by the nucleus in the presence of a magnetic field. Principle of NMR spectroscopy In an atom with an odd mass number, the proton (nucleus) spins on its own […]

Limit Test for Iron with Principle and Procedure

Limit test for iron

Limit test for iron is a semi-quantitative test used to check the iron impurities in an official sample. Principle: This test is based on the reaction of thioglycolic acid with iron in the given sample. A purple colored ferrous thioglycolate salt is formed. The color intensity is compared with that of a standard substance containing […]

Fluorimetry | Principle, Instrumentation and Applications

Fluorescence spectroscopy

Fluorimetry is a type of spectroscopy which measures the emitted radiation from a substance. This radiation is one which is emitted by the substance when the electrons transit from excited state to ground state. The principle of fluorescence spectroscopy: In UV-Visible spectroscopy, the excitation wavelength is measured. But, here the emission wavelength is measured. When […]
