High school students may be required to mix chemical solutions when encountering laboratory experiments. It is important to properly mix chemicals into a useful chemical solution. Some solutions are calculated as percent weight, w/v, or percent volume, v/v. Others are based on molarity or moles ...
pH is defined as -log [H+], where [H+] is the concentration of protons in solution in moles per liter, i.e., its molarity. If, for example, you have a 0.1 M solution of formic acid with a pH of 2.5, you can substitute this value into the pH equation: 2.5 = -log [H+] [...

Theequilibrium constant Kcis calculated using molarity and coefficients: Kc= [C]c[D]d/ [A]a[B]b where: [A], [B], [C], [D] etc. are themolar concentrationsof A, B, C, D (molarity) Read More Equilibrium Constant Definition By Anne Marie Helmenstine, Ph.D. a, b, c, d, etc...
Calculating the initial concentration of a solution – otherwise known as molarity – is an important process commonly found in the chemical and biochemical world. Molarity is the number of moles of solute per liter of solution. Therefore, you need to determine how many moles of a solute are ...
Since concentration is measured in molarity, the change in concentration is measured in M while the time is measured in seconds. This means that the units for k are usually 1/s or s-1. Stoichiometry and Reaction Rates For stoichiometry, simple reactions like the mol to mol ratio between com...
A plethora of information on the ecology and biogeochemistry of lakes is contained in the basic properties of lake water, such as electric conductivity (EC), pH, as well as major ion composition. Based on these data, not only can processes shaping lake water composition be disentangled [7],...
