Question
What is the molar hydronium ion concentration in solutions with each of the following pH values?
| (a) 1.0 | [H3O+] = M |
| (b) 5.0 | [H3O+] = M |
| (c) 9.0 | [H3O+] = M |
| (d) 12.0 | [H3O+] = M |
With the help of table below, arrange the following 0.2 M aqueous solutions in order of increasing pH:
| Name | Formula | Ka | Percent Ionization |
| Hydrofluoric acid | HF | 6.8×10-4 | 2.6 |
| Nitrous acid | HNO2 | 4.5×10-4 | 2.1 |
HF, HNO3, HNO2, KOH
HNO3, HF, HNO2, KOH
HNO3, HNO2, HF, KOH
KOH, HNO3, HF, HNO2

strong acid-weak base salt
weak acid-weak base salt
|
| b |
KC2H3O2
weak acid-strong base salt
strong acid-strong base salt
strong acid-weak base salt
weak acid-weak base salt
|
| c |
NH4NO3
weak acid-strong base salt
