So, NH4+ and NH3 are a Is an aqueous solution with OH- = 1.36 x 10-9 M acidic, basic, or neutral? Therefore, it has no effect on the solution pH. Explain. So, the only acidic salt would be HONH3Br, so it would get a ranking of "1", Next comes the neutral salt KI, with a ranking of "2", NaNO2 would have the next lowest pH so ranking "3", NH4CN would have the highest pH with a ranking of "4", This is all based on hydrolysis of the salts. 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). ; or example, hydrochloric acid is an acid because it forms H + when it dissolves in water.
