Description

When in contact with acids, ignoble metals such as magnesium dissolve to form hydrogen. If the hydrogen is collected in a time-resolved manner, this reaction can be observed very easily. In experiment C4.1.3.3 the hydrogen is collected with a piston sampler. The recording is done with CASSY, in that a displacement transducer registers the movement of the piston sampler. In this way the reaction speed can be quickly compared with different acids, e.g. hydrochloric acid and acetic acid.
