Calculate the pH which the following conversion will be at equilibrium in basic medium.
`I_(2)(s)hArrI^(-)(aq)+IO_(3)^(-)`(aq)
When the equilibrium concentrations at 300 K are `[I^(-)]=0.1M` and `[IO_(3)^(-)]=0.1M`
Given that :
`DeltaG^(@)f (I^(-),aq)=-50 kJ mol ^(-1)`
`DeltaG^(@)f (IO_(3),aq)=-123.kJ mol^(-1)`
`DeltaG^(@)f (H_2O,l) =-233kJmol^(-1)`
`DeltaG^(@)f (HO^(-),aq)=-150kJmol^(-1)`
`R=(25)/(3)JK^(-1)mol^(-1)` and ln 10 = 2.3
