Titration of a 25.00 ml amount of hbr solution with 0.250 m koh is performed. The buret holds 1.25 ml of koh at the beginning, and 28.35 ml at the end. The hbr solution has a concentration of 0.345 m hbr.
An unknown acid/base analyte solution's molar concentration (or "molarity") has to be ascertained using an acid-base titration. An accurate base/acid titrant addition from a burette is used to achieve this. Strong base KOH reacts with strong acid HBr in a 1:1 molar ratio in this acid-base titration reaction: KOH+HBrH2O+KBr
The analyte will finally be completely consumed if the titrant is kept adding. Beyond that, every additional addition will result in an excess of titrant.
