Best answer
`CH_(2)BrCIIHhArr CH_(2)BrCOO^(-)`
`{:("प्रारम्भ में सान्द्रता" ,0.1M, -),("साम्यवस्था पर सान्द्रता",0.1(1-0.132),0.1xx0.132):}`
`{:(+,H^(+)),(-,0.1xx0.132):}`
( `:.` आयनन की मात्रा `alpha=0.132)`
`:.K_(c)=([CH_(2)BrCOO^(-)][H^(+)])/([CH_(2)BrCOOH])`
`=((0.1xx0.132)xx(0.1xx0.132))/(0.1(1-0.132))`
`=2.01xx10^(-3)`
`pK_(a)=-log_(10)K_(a)=-log_(10)(2.01xx10^(-3))=2.70`
`[H^(+)]=0.1xx0.132=0.0132=1.32xx10^(-2)`
`:. pH=-log_(10)[H^(+)]=-log_(10)(1.32xx10^(-2))`
`=1.88`
