5 sie 2024 · Examiner Tip. Make sure you understand the difference between ammonium and ammonia. Ammonium refers to the aqueous cation, NH4+. Ammonia refers to the gas, NH3. Test for carbon dioxide. The test for carbon dioxide involves bubbling the gas through an aqueous solution of limewater (calcium hydoxide)
Introduction. This section continues to explores aqueous chemical reactions. First, we examine acids and bases, both strong and weak. Second, we examine neutralization reactions. Third, we examine gas-forming reactions.
(ii) basic oxide or hydroxide + acid ==> a salt + water (iii) carbonate + acid ==> a salt + water + carbon dioxide (iv) ammonia + acid ==> ammonium salt (note: no water formed, but ammonia (NH 3) is an alkaline gas and soluble in water and neutralised by acids to form ammonium salts (NH 4...)
