Can a chemical compound be both an acid and a base? vegan) just to try it, does this inconvenience the caterers and staff? Subsequently, question is, is Ki acidic basic or neutral? Cl- is a very weak conjugate base so its basicity is negligible. So yes, it is a weak acid (NH4+) and weak base (NO2-). Um, thus so a decision. CH3NH3CN is basic becouse Kb of CH3NH2 is considerbly higher than Ka of HCN.Others are correct. Routing number of commercial bank of Ethiopia?
