(g) Action of bicarbonates- It decomposes bicarbonates like NaHCO 3 to give carbon dioxide.
to give the corresponding salt and hydrogen. (f) Action of metals- Dilute H 2SO 4 reacts with metals like Zn, Fe etc. (e) Action of ammonia- It combines with ammonia to give ammonium sulfate. (d) Action of basic oxides- It reacts with basic oxides such as CaO to form the corresponding salt and water. Na 2CO 3 + H 2SO 4 -> Na 2SO 4 + CO 2 + H 2O (c) Action of carbonates- It decomposes carbonates like Na 2CO 3 forming the corresponding sulfate and carbon dioxide. NaOH + H 2SO 4 -> H 2O + NaHSO 4 (Acid Salt)ĢNaOH + H 2SO 4 -> 2H 2O + Na 2SO 4 (Normal Salt) (b) Action of alkalis- It neutralizes alkalis like NaOH to give the acid and normal slats. (a) Action of blue litmus paper- It turns blue litmus paper red. The acidic nature of the aqueous solution of acid is supported as under. Due to the formation of hydronium ions, an aqueous solution of sulfuric acid behaves as an acid.
