Brönsted acids: acidity comparison of an aqueous and an ace-tonic solution of citric acid

Principle

Acids show typical properties like the coloration of indicators or the reaction with base metals. However, substances that can form an acid only show
these properties in the form of an aqueous solution. In this experiment students study the behaviour of citric acid with regard to several substances dissolved in water and acetone.

Learning objectives

Brönsted definition of acids
Behaviour of acids dissolve in water or acetone
