Question

The reaction of ammonium hydroxide and carbonic acid results in the formation of:

• A. ammonium chloride and water
• B. ammonium carbonate and water
• C. only ammonium carbonate
• D. only water

Answer 1

Answer: (B)

ammonium carbonate and water

$\left(B\right)$ ammonium carbonate and water

$Reason$ : A reaction between a acid and a base produces a salt and water. As in the case of ammonium hydroxide($N{H}_4\left(OH\right)$) and carbonic acid($H_{2}C{O}_3$), the reaction takes place as follows -

$2N{H}_{4}OH$ + $H_{2}C{O}_3$ $\to$ $(N{H}_4{)}_{2}C{O}_3$ + $2H_{2}O$

As we can see, in the above reaction the formation of ammonium carbonate($(N{H}_4{)}_{2}C{O}_3$) and water($H_{2}O$) takes place.It is a double displacement reaction.
