Thus the charge balance equation for aqueous solution of arsenic acid, $H_{3} {AsO}_{4}$ , in which the acid can disassociate to role="math" localid="1654936784437" $H_{2} {AsO}^{-}_{4}, {HAsO}_{4}^{2 -}, {andAsO}_{4}^{3 -}$ is $H^{+} = H_{2} {AsO}_{4}^{-} + 2 [{HAsO}_{4}^{2 -}] + 3 [{AsO}_{4}^{3 -}] + {OH}^{-}$

Step by step solution

Step 1:Disassociation of an aqueous solution of Arsenic acid.

In this problem, we are in a need to write the charge balance for an aqueous solution of arsenic acid $H_{3} {AsO}_{4}$ .

We also need to note that the aqueous solution of arsenic acid can disassociate as follows,

$i . H_{3} {AsO}_{4} 鈬� H^{+} + H_{2} {AsO}_{4}^{-} ii . H_{3} {AsO}_{4}^{-} 鈬� H^{+} + H {AsO}_{4}^{2 -} iii . {HAsO}_{4}^{2 -} 鈬� H^{+} + {AsO}_{4}^{3 -} iv . H_{2} O 鈬� H^{+} + {OH}^{-}$

Step 2:Charge Balance Equation of Arsenic Acid.

The charge balance of the arsenic acid can be written as follows

H^{+} = H_{2} {AsO}_{4}^{-} + 2 [{HAsO}_{4}^{2 -}] + 3 [{AsO}_{4}^{3 -}] + {OH}^{-}

Thus the charge balance equation for aqueous solution of arsenic acid, $H_{3} {AsO}_{4}$ , in which the acid can disassociate to $H_{2} {AsO}^{-}_{4}, {HAsO}_{4}^{2 -}, {andAsO}_{4}^{3 -}$ is $H^{+} = H_{2} {AsO}_{4}^{-} + 2 [{HAsO}_{4}^{2 -}] + 3 [{AsO}_{4}^{3 -}] + {OH}^{-}$
