Ammonium Bromide is strong electrolyte when put in water: NH4Br(s) NH4+(aq) + Br(aq). magentascorpion762. WebThe methylammonium cation CH3NH3+ is similar to the ammonium (NH4+) which is somewhat acidic due to it being the conjugate acid of a weak base (NH3). CH3NH2 is a base.
acidic Why is CH3O- a stronger base than CH3NH2? Acid-base strength (in Brnsted-Lowry terms) is a relative term: an acid is strong if the position of its dissociation equilibrium lies further to the right and the stronger an acid, the weaker its conjugate base. In fact the salt Al(NO3)3 dissociate as Al+3 and NO3-. (And we have already settled whether Ca2+ or Li+ was harder.). You do so with this equation: You will see such a situation starting in the fifth example as well as scattered through the additional problems. Who are the experts? How do you know? 7.
