In chemistry, the concentration of any species is denoted by writing it in square brackets. For example, [X] means “the concentration of X.” Given the above definition of pH, the fact that a proton is simply a hydrogen atom that has lost its only electron (H+), and using the square...
The study of fundamental constituents such as atoms, molecules, substances, metals, crystals, and other aggregates of the matter is where traditional chemistry begins. Let’s now see about some basic terms of chemistry and some important chemistry terms. Chemistry Topics 118 Elements and Their Symb...
In chemistry, “mM” stands for millimolar, which is a unit used to express a solute’s concentration in a solution. Explanation: Millimolar (mM) concentrations are often used for convenience when working with solutions of small quantities of substances. One millimolar (1 mM) is equal to one...
