Question:

A 25.0 mL sample of an unknown HBr solution is titrated with 0.100 M NaOH. The equivalence point is reached upon the addition of 18.76 mL of the base. What is the concentration of the HBr solution?

Titration:

Titration is used for the motive of equivalence point detection. There are a number of different titrations. These are given below:

  • Complexometric Titration
  • Redox reaction.
  • Precipitation Reaction.
  • Acid-base titration

Titration is of great use in a number of industries such as in the wine industry and pharmaceuticals.
