Consider the ionization constants cyanic acid (hocn) : ka= 3.5×10−4; ammonia (nh3): kb= 1.8×10−5. a solution
of ammonium cyanate (nh4ocn) is 1. acidic, because the cation and the anion hydrolyze to the same extent.
2. acidic, because the anion hydrolyzes to a greater extent than the cation.
3. basic, because the cation hydrolyzes to a greater extent than the anion.
4. basic, because the anion hydrolyzes to a greater extent than the cation.
5. neutral, because the cation hydrolyzes to a greater extent than the anion.
6. neutral, because the anion hydrolyzes to a greater extent than the cation.
7. neutral, because nh4ocn is a weak base/weak acid salt. 8. basic, because the cation and the anion hydrolyze to the same extent.
9. acidic, because the cation hydrolyzes to a greater extent than the anion.
10. neutral, because the cation and the anion hydrolyze to the same extent.
