Title: is NH4+ Ammonium a strong or weak acid? and what is NH3 then?
Post by: bugmento on July 31, 2009, 10:49:36 PM

hi, i'm learning about equilibrium reactions right now, and this is confusing me:

so based on what my teacher said in class, my understanding is that NH3 (ammonia) is a strong base and its conjugate acid is NH4+ (ammonium). is this true, or am i understanding what the teacher said wrong? he said it kind of quickly so i didn't quite pick it up. also, are NH4+/NH3 those types of compounds that can be either strong or weak?

clarification of my confusion appreciated, thanks

they're both weak.
