Many, but not all, metals react with 

The essential part played by water in the characteristic properties of acids can be explored by comparing the properties of a solution of hydrogen chloride in 

The experiments in this activity can be used to show students that the familiar acidic (and alkaline) properties of some substances require the presence of water.
 

This simple experiment involves testing a variety of substances to see if they are acidic or alkaline. Litmus paper is used as the indicator.
 

Students test ethanoic acid with full-range universal
