About this app
In this lab you will find a bottle of liquid ammonium chloride, a bottle of solid ammonium chloride, a bottle of sodium hydroxide, a bottle of sulfuric acid, and indicator paper. The objective of this practice is to verify that the ammonium chloride behaves as an acid or as a base against sulfuric acid and sodium hydroxide. The pH, concentrations, and reaction constants must be measured to obtain an amount of ammonium sulfate.
