Add 1 M NaOH to raise the pH to 12 (measure with a pH meter or pH paper). If the pH drops below pH 12 during the titration, add additional NaOH. Add 4-8 drops of hydroxynaphthol blue indicator to the solution and record the color. Begin adding EDTA until the color change is observed. Record the color of the solution and the volume of EDTA ...

A more useful form of concentration for acid/base reactions is Normality. N = Also, in calculating pH, normality is used instead of molarity. but, Normality is related to Molarity: N = Ex1: Calculate the Normality and Molarity if 1.80 g of H2C2O4 is dissolved in 150 mL of. solution. Section 20.11 is not yet finished, but we’ll finish it later ...

Both the concentration in molarity (mol/L) and the volume in ml that can be converted to L of the NaOH hydroxide is known and can be used to calculate the moles of base used. At the endpoint, the number of moles of HCl used equals the number of moles of NaOH used as indicated in neutralization equation.
