If the pH of a phosphoric acid (H3PO4) solution is adjusted to 6.50, what is the most abundant species and which is the second m

maria [59]

Explanation:

For the given values of $K_{a}$ we will have the values of $pK$ as follows.

As, $pK_{a} = -log K_{a}$

Therefore,

$pK_{a1}$ = 2.15, $pK_{a2}$ = 7.20

$pK_{a3}$ = 12.38

Now, at pH 6.50

$H_{3}PO_{4} \rightarrow H_{2}PO^{-}_{4} + H^{+}$ ; $K_{a1}$

At pH = 2.15; $H_{3}PO_{4} = H_{2}PO^{-}_{4}$

$H_{2}PO^{-}_{4} \rightarrow HPO^{2-}_{4} + H^{+}$ ; $K_{a2}$

At pH 7.20; $H_{2}PO^{-}_{4} = HPO^{2-}_{4}$

$HPO^{2-}_{4} \rightarrow PO^{3-}_{4} + H^{+}$ ; $K_{a3}$

Hence, we can conclude that most abundant species is $H_{2}PO^{-}_{4}$ and the second most abundant species is $HPO^{2-}_{4}$ .
