Based on your average pka, calculate the pH of the diluted solution before adding any titrant. Does this agree with the measured pH (within 0.15 Ph UNITS) The average pka is 4.56, and the number of moles of acid is 0.00239, the amount of DI water is 60.0ml, amount of acid is 14.98ml initial, and initial ph. is 3.17. I started by finding the molarity and the Ka, Ka was 10^-4.56 and molarity of acid was 0.00239/14.98ml + 60.0 ml times (1000ml/1L) How do you finish this?
