0.7 mol of H⁺ ions are present in 2.8 l of 0.25 m hydrobromic acid solution.
Hydrobromic acid is a strong acid, we can assume that all acid molecules dissociate completely to yield H+ ions and dissociated anion.
<h3>The equation for the dissociation of HBr :</h3>Hbr <em>(s) → </em>H⁺ <em>(aq) </em>+ Br⁻<em> (aq)</em>
<em></em>
moles H⁺ = () (
) (
) (
)
= 0.7 mol
Therefore, 0.7 mol of H⁺ ions is present.
