9. Acid-Base Titrations Acid-Base titrations are performed to determine the concentration of an acid or base in a solution When the number of moles of in an acid is equal to the moles of in the base, water is formed and no acid or base is left unreacted. The solution has a pH of 7 and is called neutral. In an acid-base titration we use this concept to find out the concentration of an acid by adding base until all...
