Consider the titration of a 35.0-mL sample of 0.175 M HBr with 0.200 M KOH. Determine each quantity. b. the volume of added base required to reach the equivalence point

Key Concepts

Titration

Titration is a quantitative analytical technique used to determine the concentration of a solute in a solution. It involves the gradual addition of a titrant (a solution of known concentration) to a sample until the reaction reaches its equivalence point, where the amount of titrant added is stoichiometrically equivalent to the amount of substance in the sample.

Equivalence Point

The equivalence point in a titration is the stage at which the amount of titrant added is exactly enough to completely neutralize the analyte in the solution. At this point, the moles of acid equal the moles of base, and it is often indicated by a color change in an appropriate indicator or by measuring pH.

Stoichiometry

Stoichiometry is the calculation of reactants and products in chemical reactions based on the balanced chemical equation. It allows for the determination of the relationships between the quantities of substances involved, which is essential for calculating the volume of titrant needed to reach the equivalence point in a titration.
