What will be the change in pH by adding of 0.1 M NH_4Cl in 0.1 M NH_4OH (weak base) solution ? (K_b of NH_4OH = 1.77xx10^(-5) )

What will be the change in pH by adding of 0.1 M NH_4Cl in 0.1 M NH_4O

1.	What will be the change in pH by adding of 0.1 M NH_4Cl in 0.1 M NH_4OH (weak base) solution ? (K_b of NH_4OH = 1.77xx10^(-5) )
Answer» SOLUTION :PH of `NH_4OH = 11.12` , pH of `NH_4Cl`= 9.251 DECREASE in pH = 1.87
