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

Answer:
to the right (products side)
Explanation:
The equilibrium constant K describes the ratio between the concentration of products and reactants at equilibrium. For a general reaction:
a A + b B → c C + d D
The equilibrium constant expression is:
A low value of K indicates that the concentration of products (C and D) is low in relation with the concentration of reactants (A and B).
Conversely, a high value of K indicated that the concentration of products is high compared with the concentration of reactants.
Since K = 6.4 × 10⁹ is a high value, the concentration of products is higher than the concentration of reactants at equilibrium. Thus, the position of the equilibrium is favored to the right.
