# How would you complete and balance the acid base neutralizations reaction: HI + KOH ->?

Mar 27, 2017

$\text{Acid + base "rarr" salt and water}$

#### Explanation:

And thus:

$H I \left(a q\right) + K O H \left(a q\right) \rightarrow K I \left(a q\right) + {H}_{2} O \left(l\right)$

Because the potassium and iodide salts are along for the ride, we could write the net ionic equation as:

${H}^{+} + H {O}^{-} \rightarrow {H}_{2} O \left(l\right)$

OR

${H}_{3} {O}^{+} + H {O}^{-} \rightarrow 2 {H}_{2} O \left(l\right)$

Are $\text{mass}$ and $\text{charge}$ balanced in each instance? If they are not, you know that it cannot be accepted as a representation of chemical (i.e. physical) reality.
