Calculate `[OH^(-)]and %` dissociation of 0.01 M solution of ammonium hydroxide solution. The ionization constant for `NH_(4)OH(K_(b))=1.8xx10^(-5)` |
Answer» `{:(NH_(4)OH,hArrNH_(4)^(+)+,OH^(-)),(C-Calpha,C alpha,Calpha):}` `K_(b)=([NH_(4)^(+)][OH^(-)])/([NH_(4)OH])` `K_(b)=(Calpha^(2))/(1-alpha)` `1.8xx10^(-5)=(0.01xxalpha^(2))/(1-alpha)` `alpha=sqrt(1.8xx10^(-3))=4.24xx10^(-2)[1-alpha=1]` `%` dissociation `=4.24` `[OH^(-)]=Calpha=0.01xx4.24xx10^(-2)` `[OH^(-)]=4.24xx10^(-4)M` |
