Calculate the pH at the equivalence point of a 0.125 M solution of (CH3)2NH (dimethylamine) titrated with 0.125 M HCl. A volume of 0.125 M HCl equal to that of 0.125 M (CH3)2NH was used to achieve equivalence. Determine the suitable indicator for the said titration. The Ka for (CH3)2NH2+ is 1.86×10−11.
