Explanation / Answer
From the lowest to the highest hydroxide-ion concentration: HBr < NH4Cl < KBr <CH3NH2Out of all CH3NH2 is thehighest OH- producer. KBr is salt of strong base & strong acid. So it is thenext highest OH- producer and NH4Cl is weaklyacidic , HBr is strong acid. So they come in the nextpositions.
