I'm trying to calculate the pH of an acid base titration at the equivalence point. I observed a pH of 8.05 with 22.29 mL of NaOH in 25 mL of HCl diluted in 48.84 mL of water. The molarity of the NaOH is .1086 and the molarity of the HCl before dilution is .1001 M. I've been trying to figure this out for days and it's due tomorrow. Please help me.
