## 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.
