Consider the ionization constants cyanic acid (HOCN) : Ka = 3.5 104; ammonia (NH3) : Kb = 1. A solution of ammonium cyanate (NH4OCN) is 1.
Consider the ionization constantscyanic acid (HOCN) : Ka = 3.5 × 10−4; ammonia (NH3) : Kb = 1.8×10−5. A solution of ammonium cyanate (NH4OCN) is1. acidic, because the anion hydrolyzes to a greater extent than the cation.2. acidic, because the cation hydrolyzes to a greater extent than the anion.3. neutral, because the cation and the anion hydrolyze to the same extent.4. acidic, because the cation and the anion hydrolyze to the same extent.5. neutral, because the cation hydrolyzes to a greater extent than the anion.6. basic, because the cation and the anion hydrolyze to the same extent.7. neutral, because NH4OCN is a weak base/weak acid salt.
