A 1L solution contains 0.2M `NH_(4)OH` and 0.2M `NH_(4)Cl.` If 1.0 mL of 0.001 M HCl is added to it what will be the `[OH^(-)]` of the resulting solution `(K_(b)=2xx10^(-5))`

A solution consists of 0.2 M NH_4 OH and 0.2 M NH_4Cl . If K_b of NH_4 OH is 1. 8 xx 10 ^(-5) , the [OH^(-) ] of the resulting solution is

A solution consist of 0.2 M NH_(4)OH and 0.2 M NH_(4)Cl . If K_(b) of NH_(4)OH is 1.8 xx 10^(-5) , the [OH^(-)] of the resulting is

50 ml of 0.2 M NH_(4)OH and 50 ml of 0.2 M HCl solutions are Mixed. pH of the resulting solution is (Given Kb of NH_(4)OH=1 times 10^(-5) )

A buffer solution contains 0.25M NH_(4)OH and 0.3 NH_(4)C1 . a. Calculate the pH of the solution. K_(b) =2xx10^(-5) .
