Which of the following expressions is correct?

A

`wedge_(m)^(infty)(NH_(4)OH) = wedge_(m)^(infty)(NH_(4)Cl) + wedge_(m)^(infty)(NaOH)-wedge_(m)^(infty)(NaCl)`

B

`wedge_(m)^(infty)(NH_(4)OH) = wedge_(m)^(infty)(NH_(4)Cl)-wedge_(m)^(infty)(NaOH)+wedge_(m)^(infty)(NaCl)`

C

`wedge_(m)^(infty)(NH_(4)OH) = wedge_(m)^(infty)(NH_(4)Cl)-wedge_(m)^(infty)(NaOH)-wedge_(m)^(infty)(NaCl)`

D

`wedge_(m)^(infty)(NH_(4)OH) = wedge_(m)^(infty)(NH_(4)Cl) + wedge_(m)^(infty)(NaOH) + wedge_(m)^(infty)(NaCl)`

Text Solution

Verified by Experts

The correct Answer is:
B

`wedge_(m)^(@)(NH_(4)OH)=wedge_(m)^(@)(NH_(4)^(+))+lambda_(m)^(infty)(OH^(-))`
`wedge_(m)^(@)(NH_(4)CI)+wedge_(m)^(@)(NaOH)-wedge_(m)^(infty)(NaCI)`
