Just nitrogen gets protonated, that's where the cation comes from. So let's go ahead and write that down. Explain. I think the 'strong base if weak conjugate acid' argument only really works if the conjugate acid is less acidic than water. Since Kb for NH3 is greater than the Ka for HCN,( or Kb CN- is greater than Ka NH4+), this salt should have a pH >7 (alkaline). The question doesn't give any information about CH3NH2+ and I don't see it in the book's appendix, So something-NH2 gets protonated to something-NH3+. Is a solution with OH- = 2.21 x 10-7 M acidic, basic, or neutral? The reverse is true for hydroxide ions and bases.
