A solution consists of 0.2 MNH_4 OH and 0.2 MNH_4Cl .If K_b of NH_4 OH is 1. 8 xx 10 ^(-5), the [OH^(-) ] of the resulting solution is

A solution consists of 0.2 MNH_4 OH and 0.2 MNH_4Cl .If K_b of NH_4 OH

1.	A solution consists of 0.2 MNH_4 OH and 0.2 MNH_4Cl .If K_b of NH_4 OH is 1. 8 xx 10 ^(-5), the [OH^(-) ] of the resulting solution is
Answer» `0.9 XX 10 ^(-5) M` ` 1.8 xx 10 ^(-5) ` ` 3.2 xx 10 ^(-5) M` ` 3. 6 xx 10 ^(-5) ` M SOLUTION :`POH =P^(K_b)+ log ""( [S])/([B]) ` If ` [S] =[B] rArr pOH = P^(K_b) rArr [OH^(-) ] =K_b`
