Description

The carboxylic acid tartaric acid is naturally present in many fruits. Its potassium salts are called tartar. Tartaric acid and tartar are used as acidifiers.

In this experiment, the students mix tartrate or tartaric acid with sodium hydrogen carbonate to make sherbet and baking powder, respectively. The students compare the reactions of the mixtures with water. This will help them to recognise which mixture can be used as an effervescent tablet and which as a baking powder.
