Test for hydrogen Squeaky pop Test for a Carbonate anion (CO32-) React with an acid to release carbon dioxide gas. Effervescence is observed and the production of carbon dioxide can be confirmed using limewater. ALTERNATIVLEY: A solution of a carbonate will also be alkaline, which can be shown using universal indicator or a pH probe. Ionic equation when testing for a carbonate anion: 2H+(aq) + CO32−(aq) → H2O(l) + CO2(g) Silver compounds are all ______________ except for ________...
