3. TITRATION Titration is a technique to determine the concentration of an unknown solution . Titration is the slow addition of one solution of a known concentration (called a titrant or titrator) to a known volume of another solution of unknown concentration (called a titrand or analyte) until the reaction is completed , which is often indicated by a color change.

4. RADIOMETRIC TITRATION When a titration involve radioactive reagent it is called radiometric titration. Radiometric titration is a quantitative method for the determination of an element.

5. Elements of Titration . . . Standard solution : The solution of known concentration. An accurately measured amount of standard solution is added during titration. The analyte : The solution of unknown concentration is known as the analyte.

6. The equivalence point: The equivalence point is the ideal point for the completion of titration. The end point: It indicates once the equivalence point has been reached. It is indicated by some form of indicator (Colour).

7. The calibrated burette: it is the main piece of equipment required for a titration method. Calibration is important. Therefore we use calibrated burette for this purpose.

8. The Indicator: Usually used to determine the end point. These are colour substances. Indicators must only be added to the solution of unknown concentration when no visible reaction will occur.

9. CONDITIONS Radioactive isotope is easily formed compound. The activity of the titrant should be significantly change by the addition of other compound.

10. The end point of the titration should have minimum or maximum activity. Titration does not favour the other compound formation, i.e; Side reaction is not possible. RMT should be form a less soluble or removal compound in the titration.

11. APPLICATIONS Determination of the Composition of compound. Investigation of Co-precipitation Determination of the specific activity of Radioactive preparations.
