Question

How many moles of h+ ions are present in 2.8 l of 0.25 m hydrobromic acid solution?

Answer 1

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.

The equation for the dissociation of HBr :

                             Hbr (s) →  H⁺ (aq)  +  Br⁻ (aq)

moles H⁺ = ($2800ml$) ( $\frac{1L}{1000ML}$)  ($\frac{0.25 mol Hbr}{L}$) ( $\frac{1 mol H}{1 mol Hbr}$)

               = 0.7 mol

Therefore, 0.7 mol of H⁺ ions is present.
