WebMolarity(M) is a measure of concentration in terms of the mole and is moles of a substance per liter (mol/L) of solution. 1 M solution of NaCl would be 58.44 g/L of NaCl. An equivalent is 1 mol of reactive species, whether it is an H+of acid–base reactions, an electron of reduction–oxidation reactions, or some other unit. WebBuffer Capacity 1 M NaOH is added incrementally to beakers containing DI water, and 0.01 M, 0.1 M, and 1 M acetate buffer solutions to which universal indicator has been added. The DI water changes dramatically with the addition of a single drop.
