Question

Consider the ionization constants cyanic acid (HOCN) : Ka= 3.5×10−4; ammonia (NH3): Kb= 1.8×10−5. A solution

Answer 1

The correct answer for this question is this one:

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.
5. neutral, because the cation hydrolyzes to a greater extent than the anion.
7. neutral, because NH4OCN is a weak base/weak acid salt. 8. basic, because the cation and the anion hydrolyze to the same extent.
10. neutral, because the cation and the anion hydrolyze to the same extent.
Hope this helps answer your question and have a nice day ahead.
