Learning Goals
Here the learning goals and purpose of the exercise should be presented in a reasonable way.

Theory
Tracers and solubility

Experimental Procedure
Experimental procedure for determination of low solubilities

Questions for the Students
1. What are the sources of errors? 2. Highlight the potential problems of using 90 Sr for this experiment.

Other
How to do calculations or other important aspects for the theory that is not directly related to exercise.

Safety Aspects

 * A lab coat, gloves and safety spectacles must be worn. 35 S is a soft beta emitter which means that it is not readily detected. When checking the bench, hands, lab coat, etc for contamination it is necessary to use a sensitive instrument.
 * **DO NOT** dispose of any liquid or solid waste down sinks or in waste bins. Place in the waste buckets provided.

Equipment
Centrifuge glass beaker x 2 for H 2 O Scintillation counter waste beaker 1 mL pipette Polystyrene base to stand centrifuge tubes in 25 mL volumetric flask 4-5 mL 2 M sulphuric acid 15 mL centrifuge tubes x 2 > 100 mL dH 2 O Scintillation vials x 5 50 mL Scintillation fluid 1 mL tips
 * Consumables **

4 mL 35 S strontium nitrate @ 0.28 kBq per mL
 * Source **

Preparation for the lab Supervisor
The preparation that the lab Supervisor needs to do to ready the lab.
