What is the concentration of the acid if the initial burette reading is 2.14 mL and the burette reading when the endpoint observed was 21.62 mL?
A 25.00 mL sample of hydrochloric acid solution of unknown concentration was titrated with 0.09899 M NaOH solution.

0.07713 M
Explanation:
at equivalence point,
(MHCl)(VHCl) = (MNaOH)(VNaOH)
Volume of NaOH used
= 21.62 - 2.14
= 19.48 mL
MHCl =
MHCl =
MHCl = 0.07713 M
