Learning Goals

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

Explanation and Exercise Guide

Theory

Ion exchange on insoluble crystal surfaces

Experimental Procedure

Experimental procedure for determination of the specific surface are of an insoluble substance

Questions for the Students

Here there should be relevant questions regarding the theory of the exercise which should be possible to answer after the exercises have been performed. The questions should be molded into the report that the students write after the exercises in such a way that it feels natural.

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 glasses 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 red waste buckets provided.
• Lead sulphate is toxic by ingestion, inhalation and skin contact. When weighing out the powder, great care must be taken to avoid creating air-borne dust.
