Acid-Base Titrations Molarities of acidic and basic solutions can be used to convert back and forth between moles of solutes and volumes of their solutions, but how are the molarities of these solutions determined? This section describes a procedure called titration, which can be used to find the molarity of a solution of an acid or a base. standardization. (iii) Acid-Base Titration and End Point . When exact stoichiometric amounts of acid and base have been mixed, the reaction is said to have reached the equivalence point. Essentially all of the acid has reacted with the base, and vice versa. Experiment # 5 …

Normality is the number of equivalents per liter of solution (#eq/L soln). Titration Procedure Standardizing a Base. Suppose that you needed a 0.1000 M solution of NaOH to do a titration. You might think that you could just weigh 4.000g of solid NaOH and dissolve it in enough water to make 1.000 L of solution.
