Learning Goals

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

Explanation and Exercise Guide

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 90Sr 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. 35S 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
