0.05 mole

B

0.025 mole

C

0.10 mole

D

0.0005 mole

Text Solution

Verified by Experts

The correct Answer is:
2
`pH=pK_(a)+log.(["Base"])/(["Salt"])`
`[Base]=(0.01xx500)/(500)=0.01`
`[NH_(4)^(+)]=(axx2)/(500),` Let a millimole of `(NH_(4))_(2)SO_(4)` are added
`:." "[Sal t]=[NH_(4)^(+)]`.
`pH=9.26+log[(0.01)/(2a//500)]`
`8.26=9.26+log.(0.01xx500)/(2a)`
`a=25" ":." "` Mole of `(NH_(4))_(2)SO_(4)` added `=0.025`
