In a titration experiment, hcl and lioh solutions were used. the initial volume of hcl was 1.25ml and lioh was 2.65 ml. the final volume of hcl was 13.60 ml and lioh was 11.20 ml. if the lioh was 0.140 m what was the molarity of hcl?

Answer is: the molarity of HCl is 0.097 M.

Chemical reaction: LiOH + HCl → LiCl + H₂O.

V (HCl) = 13.60 mL - 1.25 mL = 12.35 mL.

V (LiOH) = 11.20 mL - 2.65 mL = 8.55 mL.

c (LiOH) = 0.140 M.

From chemical reaction: n (LiOH) : n (HCl) = 1 : 1.

c (HCl) · V (HCl) = c (LiOH) · V (LiOH).

c (HCl) = 8.55 mL · 0.140 M / 12.35 mL.

c (LiOH) = 0.097 M.
