Weak acids and bases are not completely ionised when dissolved in polar medium like water
`H rarr H^(+) +A^(-)`
`{:(t_(0),C,O,O),(t_(eq),C-Calpha,Calpha,Calpha):}`
`K_(a)=(Calpha^(2))/(1-alpha)=Calpha^(2),alphasqrt((K_(a))/(C))`
`:. (alpha_(1))/(alpha_(2))=sqrt((Ka_(1))/(Ka_(2))),(alpha_(1))/(alpha_(2))=sqrt((C_(2))/(C_(1)))`
( For two acids at same conc.) (for same acid at diff conc. )
0.01M `CH_(3),COOH` is 4.24% ionised. What will be the pereentage ionisation of 0.1 `M CH_(3),COOH.`
