What m and M Mean in Chemistry. Both m and M are units of the concentration of a chemical solution. The lower case m indicates molality, which is calculated using moles of solute per kilograms of solvent. A solution using these units is called a molal solution (e.g., 0,1 m NaOH is a 0.1 molal solution of sodium hydroxide).
What does pH stand for and. To answer what does pH stand for is pretty straight forward. The p stands for potential and H stands for hydrogen. The definition of pH is the negative logarithm of the hydrogen (H+) ion activity in a given solution. By virtue of its logarithmic nature, pH is a dimensionless quantity. The purpose of the negative sign in the equation is to give a positive pH value.
