What Is pH? pH is a measure of the acidity or basicity of a solution. The acidity or basicity of any solution is defined by its concentration of protons. So, mathematically, pH is the negative log to base 10 of the proton concentration. In chemistry, the concentration of any species ...
What does a Ph.D. in chemistry get you?Janet D. Stemwedel
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...
Chemistry is a physical science, which means it doesn't involve "living" things. One way a lot of people practice chemistry regularly, perhaps without realizing it, is in cooking and baking.(Image credit: Shutterstock) The five main branches of chemistry ...
Well, it looks like Mrs. Kennedy had the last laugh – pH is something that I now regularly monitor in my aquarium. And today I am going to teach you how to do the same! So read on to learn everything you ever wanted to know about your aquarium’s pH!
pH is an index to evaluate the acidity and basicity of solutions. pH stands for the "power of hydrogen" and is calculated by taking a negative logarithm from the molar concentration of the hydrogen ion in the solution. At 25 degrees Celsius, the equilibrium constant of water self ioni...

pH measurement is an important parameter in nearly every water quality application. In environmental sampling and monitoring, high or low pH values can be indicative of pollution. To determine the pH of water, a pH meter can be used to measure this impor
If you look 'chemistry' up in Webster's Dictionary, you'll see the following definition: "chem·is·try n., pl. -tries . 1. the science that systematically studies the composition, properties, and activity of organic and inorganic substances and various elementary forms of matter ...
