C is answer amonimghjvvbvjjjjj

Answer 2

Answer:

Acid reacts with carbonate to form carbon dioxide. It  is not characteristic property of a base.

Therefore, the option (A) is correct.

Explanation:

• When a base reacts with an acid. There will be the formation of water and salt. This reaction is called neutralization reaction. For example:

       $NaOH \;+ HCl \; \longrightarrow\; NaCl \; +\; H_{2}O$

• When an aqueous solution of base is treated with ammonium salt. The product formed are ammonia, water and salt. For example:

       NaOH(aq.)  +  NH₄Cl  $\longrightarrow$  NH₃  + H₂O  +  NaCl

• Base turns the red litmus paper into blue while acid turns blue litmus paper into red.
• Acids react with carbonate and produce carbon dioxide, not bases.

        2HCl (aq)  +  CaCO₃(aq)   $\longrightarrow$   CO₂(g)  +  CaCl₂(aq)  + H₂O (l)

Therefore, reaction with carbonate to produce CO₂, is not the characteristic property of bases.
