Answer: Titration is particularly useful if we want to find out the amount or concentration of a known acid or base in a given sample.
Explanation: Suppose you have just been handed a beaker containing a fixed volume of HCL solution. If you simply just know the volume of the solution, you can titrate it against a reagent (base) to figure out the exact concentration of the solution (also known as molarity)
The solution is placed in a flask for titration and a minute amount of indicator is then added into the flask. The reagent (base) is placed in a burette and slowly added to the solution and indicator mixture. The amount of reagent used is recorded when the indicator causes a change in the color of the solution. Using Stoichiometry, we are then able to calculate the concentration and moles of the HCL solution used up in the reaction.
