Let's analyze the given question step-by-step.
We have the reactants in a neutralization reaction:
[tex]$
Ca ^{2+} + OH ^{-} + H ^{+} + NO _3^{-} \rightarrow ?
$[/tex]
In a neutralization reaction between an acid and a base, the hydrogen ion ([tex]\(H^+\)[/tex]) from the acid generally combines with the hydroxide ion ([tex]\(OH^-\)[/tex]) from the base to form water ([tex]\(H_2O\)[/tex]).
1. Identify the ions involved: We have the following ions in the reactants:
- [tex]\(Ca^{2+}\)[/tex] (Calcium ion)
- [tex]\(OH^{-}\)[/tex] (Hydroxide ion)
- [tex]\(H^{+}\)[/tex] (Hydrogen ion)
- [tex]\(NO_3^{-}\)[/tex] (Nitrate ion)
2. Determine the role of each ion:
- [tex]\(H^{+}\)[/tex] (Hydrogen ion) will typically bind with [tex]\(OH^{-}\)[/tex] (Hydroxide ion) to form water in a neutralization reaction.
3. Reaction outcome:
- The [tex]\(H^{+}\)[/tex] and [tex]\(OH^{-}\)[/tex] will combine to form water:
[tex]$ H^{+} + OH^{-} \rightarrow H_2O $[/tex]
Thus, the correct description of what will happen to the [tex]\(H^+\)[/tex] is:
[tex]$ H^{+} \text{ binds with } OH^{-} \text{ to make water.} $[/tex]
Therefore, out of the given options:
1. [tex]\(H^{+} \text{ binds with } NO_3^{-} \text{ to make a salt.}\)[/tex] - Incorrect.
2. [tex]\(H^{+} \text{ binds with } Ca^{2+} \text{ to make an acid.}\)[/tex] - Incorrect.
3. [tex]\(H^{+} \text{ binds with } OH^{-} \text{ to make water.}\)[/tex] - Correct.
4. [tex]\(H^{+} \text{ binds with } Ca^{2+} \text{ to make a base.}\)[/tex] - Incorrect.
The correct statement is:
[tex]$ H^{+} \text{ binds with } OH^{-} \text{ to make water.} $[/tex]
Hence, the answer is option 3.
