Arrange the following 0.10M solutions in order of increasing pH:

a. Nacl
b. NH4CL
C. HCL
D. NaCH3CO2
e. KOH

1 answer

The pH is determined by the hydrolysis of the salt(for salts) or the reactin with water (as in HCl and KOH). For example,
KOH is a strong base; ie., it ionizes 100% so K^+ = OH^- = 0.1M.
NaC2H3O2 is the salt of a strong base (NaOH) and acetic acid (HC2H3O2) The Na^+ is not hydrolyzed but the acetate ion (C2H3O2^-) is. Etc. Please explain what your trouble is in answering this question so I will know how to explain.
The correct order is
HCl, NH4Cl, NaCl, NaC2H3O2, KOH
