Question

Statement: Titer value is the volume of titrant used for a definite amount of unknown reagent at its equivalence point.

State whether the given statement is true or false.

• A. True
• B. False

Answer 1

The correct option is A True

The titre value is the volume of titrant used for a definite amount of unknown reagent at its equivalence point.
For example, a titration between Oxalic acid and $KMn{O}_4$ in acidic medium, as follows:

$5C_2{O}_4^{2-}+2Mn{O}_4^{-}+16H+\to 2M{n}^{2+}+10C{O}_2+8H_{2}O$

If here, the concentration of oxalic acid is known then, it is called titrant, as using its solution with unknown reagent will give the amount (volume ) of $KMn{O}_4$ solution, at the equivalence point.
So here, the volume used for the oxalic acid solution (also called standard solution as its concentration is taken as known concentration) to react completely with $KMn{O}_4$ solution at the equivalence point, is called the titre value.

Hence, the given statement is $\text{true}$
