Question

Как экспериментально различить растворы аммоний карбона и аммоний сульфата

Answer 1

Ну тут относительно просто, температура распада NH4SO4 около 150°, NH4CO3 - крайне неустойчивое соеденение, может распадаться даже при комнатной температуре.
Немного нагреваем обе пробирки (хватит 60°), та из которой начнет игтенсивно выделяться газ - NH4CO3.
Та что не изменится - NH4SO4

Answer 2

Distinguishing Between Ammonium Carbonate and Ammonium Sulfate Solutions

To experimentally differentiate between ammonium carbonate and ammonium sulfate solutions, you can use the following methods:

1. Reaction with Barium Chloride: - Add a few drops of barium chloride solution to a small amount of the unknown solution. - Observation: A white precipitate indicates the presence of sulfate ions, confirming the solution as ammonium sulfate. - Source: 2. Reaction with Hydrochloric Acid: - Add a few drops of dilute hydrochloric acid to a small amount of the unknown solution. - Observation: Effervescence (formation of bubbles) indicates the presence of carbonate ions, confirming the solution as ammonium carbonate. - Source: These experimental methods allow for the differentiation of the two solutions based on their chemical reactions with specific reagents.
