Examples of bases are the hydroxides of the alkali metals and the alkaline earth metals (NaOH, Ca(OH)2, etc. —see alkali hydroxide and alkaline earth hydroxide).For testing the presence of a base in a substance, we can use acid-base indicators such as litmus paper. If u dip blue litmus paper into an acidic solution, its colour will change to red and vice versa for the basic solution.May 28, 2018
