Beschreibung:
A good way to introduce the subject of acids and bases to students is in relation to our body: the tongue as a taste sensor, the acid mantle of the skin, soap in the eyes, acid burps, etc.
We can refer to natural and artificial dyes as “sensors” for acids and bases.
By the way, base is the general term whereas alkalis (they contain alkali metals) are a subset of basic substances.
One item deals with „Technical application and vocational orientation“.
