1) a 100ml smaple of 0.18M HCLO4 is titrated with 0.27M LiOH. determine the ph of the soution after the addition of 66.67 ml of LiOH (this is at equivalence point)
2)a 100 ml sample of .20M HF is titrated with .10M KOH. determine th ph of the soution before the addition of any KOH. the Ka of HF is 3.5 e-4
1. Since it's at the equivalence point, the pH will be 7.00!
