In the eqantitative analysis `Bi^(3+)` is detected precipitation of `[BiO (OH)(s)]` [bismuthy`1` hydroxide). Calculate the `pH` when the following equilibria exists:
`BiO (OH)(s) hArr BiO^(o+)(aq) + overset(Theta)OH (aq) (K = 4 xx 10^(-10))`

Text Solution

Verified by Experts

`[overset(Theta)OH] [BiO^(o+)] = 4 xx 10^(-10)`
`:. [overset(Theta)OH]^(2) = 4 xx 10^(-10) :. [overset(Theta)OH] = 2 xx 10^(-5)`
`:. pOH = 4.6989 :. pH = 9.3010`
