Assume negliglible ionization to determine the percent ionization of each of the following acids and then indicate whether the assumption was valid.
a) 0.030 M solution of cyannic acid (HCNO, pKa = 3.46)
% ionization = valid:
---Select---
Yes
No
b) 0.0043 M solution of hydroazoic acid (HN3, pKa = 4.60)
% ionization = valid:
---Select---
Yes
No
c) 0.010 M solution of benzoic acid (HC7H5O2, pKa = 4.19)
% ionization = valid:
---Select--
Yes
No
