Five solutions at the same temperature and with the same concentrations, sucrose (table sugar), nitric acid, ammonia solution, sodium hydroxide and methanoic acid, were tested with universal indicator. Suggest which of these solutions should be matched to each pH measurements listed in the table, and information about the properties of these substances that guided your identifications.
