Question

Dilute hydrochloride acid, dilute nitric and sulphyuric acid all react with??
(a) aqueous barium chloride to give a precipitate.
(b) copper to give hydrogen.
(c) aqueous silver nitrate to give a precipitate.
(d) aqueous sodium carbonate to give carbon dioxide.
Please choose the correct answer !!! and Explain.

Answer 1

Answer:

D)aqueous sodium carbonate to give carbon dioxide

Explanation:

With hydrochloric acid

Na2CO3 (s) + 2HCl (aq) → 2NaCl (aq) + CO2 (g) + H20

With sulphuric acid

Na2CO3 (s) + H2SO4 (l) → Na2SO4 (aq) + CO2 (g) + H20  

Answer 2

Answer:

• The answer is option D which is Aqueous Sodium Carbonate to give Carbon dioxide.

• Hydrochloric acid: Na2CO3 (s) + 2HCl (aq) = 2NaCl (aq) + CO2 (g) + H2O.

• Sulphuric acid: Na2CO3 (s) + H2SO4 (l) = Na2SO4 (aq) + CO2 (g) + H2O.
