Weak Electrolyte and Weak Base: Ammonia

CHEM-QL1SSY

Ammonia ($N{ H }_{ 3 }$) is a weak electrolyte and a weak base.

Which of the following equations explains these facts BEST?

A

$N{ H }_{ 3 }(aq)\space +\space { H }_{ 2 }O(l)\space \longrightarrow \space N{ H }_{ 4 }^{ \space + }(aq)\space +\space { H }^{ + }(aq)$

B

$N{ H }_{ 3 }(l)\space \rightleftharpoons \space N{ H }_{ 2 }^{ \space - }(l)\space +\space { H }^{ + }(l)$

C

$N{ H }_{ 3 }(g)\space \rightleftharpoons \space N{ H }_{ 2 }^{ \space - }(g)\space +\space { H }^{ + }(g)$

D

$N{ H }_{ 3 }(aq)\space +\space { H }_{ 2 }O(l)\space \rightleftharpoons \space N{ H }_{ 4 }^{ \space + }(aq)\space +\space { H }^{ + }(aq)$
