1.	When `NH_(4)Cl` is added to a solution of `NH_(4)OH :`A. the dissociation of `NH_(4)OH` increasesB. the concentration of `OH^(-)` increases.C. the concentration of both `OH^(-)` and `NH_(4)^(+)` increaseD. the concentration of `OH^(-)` ion decreases.
Answer» Correct Answer - D `NH_(4)ClhArrNH_(4)^(+)+Cl^(-)" "," "NH_(4)OHhArrNH_(4)^(+)+OH^(-)` Because of common ion effect , the ionisation of `NH_(4)OH` is suppressed.
