The titration endpoint occurs when the methyl red indicator changes from a yellow to a salmon pink color. The amount of HCl needed to titrate each sample should decrease significantly for each sample (1-5) as the concentration of borax in each 5 mL sample decreases with temperature.

In strong acid/strong base titrations, the equivalence point is found at a pH of 7.00. In titrations with a weak base and a strong acid, the pH will always be less than 7 at the equivalence point because the conjugate acid of the weak base lowers the pH.
