Who uses a titration?

Question

When is a titration used?

Answer 1

Titration can be used to find the concentration of an unknown solution, using a standard solution of which the concentration is known.

However there are limitations:
- The reaction mechanism between the two must be known, and the exact equation must be known.
- The standard solution must be made up exactly and accurately so the concentration is exact.
- There must be some sort of colour change to indicate the endpoint of the reaction, (adding indicators, coloured ion formation etc.)

A good example of use is determining the concentration of iron in blood by reacting it with potassium manganate, although more sophisticated techniques are in use nowadays.

Answer 2

A titration is used when a solution of known concentration can be added to and react with another material that is of unknown concentration. The volume of the addion of the solution has to be able to be measured.

The known concentration material must react in a known proportion to the unknown material so that the amount of the unknown can be determined.

There must be some way to know when the unknown has been fully consumed so that more of the known solution is not added.

Let's say the reaction of the known, K to the unknown, U is 2:1 (2 moles K reacts with 1 mole U). Let's assume that the known concentration is 0.1 M and that we consume 35 ml of the solution in the titration.

This means that we consumed 35 ml X 0.1 mmole/ml = 3.5 mmole of K. Because of the 2:1 ratio, this means there is 1.75 mmoles of U in the sample.

Titration is used when there is a clear, known molar ratio of known to unknown, when there is a way to determine end point, and when the reaction is rapid.

Answer 3

It is used in neutralisation reactions. The acid normally goes in the burette and the alkali goes underneath in a conical flask, usually with an indicator in the solution if required. You then add the acid slowly from the burette whilst swirling the conical flask. Stop titrating when you see the appropriate colour change and record the amount of acid required for the neutralisation to occur.

Titrations can also be used to determine the concentrations of known reactants.

Hope that helps!

Answer 4

Titration procedures are used in quantitative chemical analysis. Because the technique is easy to learn and the equipment required is not expensive, many labs in industry routinely use various titration procedures.
