The degree of decomposition depends greatly on the storage conditions. The statements in the exemplary solutions are therefore only examples of observations which could be made.

The theme "preservatives" can be discussed in general in this connection. The students could collect information on preservatives on food Iabels and examine their chemical content.

Learning objectives

• Formic acid inhibits the growth of bacteria and fungi.
• It is therefore used as a preservative for foods.

Benefits

• Easy teaching and efficient learning by using interactive experimentation PHYWE-Software
• Experiment is part of a complete solution set with experiments for the topic Organic Chemistry matched with international curriculum: all topics are covered
