The compound NaOH(s) dissolves in water to yield
(1) hydroxide ions as the only negative ions
(2) hydroxide ions as the only positive ions
(3) hydronium ions as the only negative ions
(4) hydronium ions as the only positive ions

Sagot :

Answer: Option (1) is the correct answer.

Explanation:

Sodium hydroxide is a strong base and when it is dissolved in water it completely dissociates into ions.

The chemical equation for this dissociation is as follows.

           [tex]NaOH(s) + H_{2}O(l) \rightarrow Na^{+}(aq) + OH^{-}(aq)[/tex]

Therefore, we can see that sodium ions are the only positive ions and hydroxide ions are the only negative ions formed upon dissociation of NaOH in water.

Thus, we can conclude that the compound NaOH(s) dissolves in water to yield hydroxide ions as the only negative ions.
