Calculate the pH of a solution that is 0.145 M in a propanol
acid (CH3CH2COOH) and 0.127 M in potassium propanoate (KCH3CH2COO).
The Ka of propanoic acid is 1.34x10^-5. Your answer should be
reported in three significant figures.
Calculate the pH and pOH of a
0.50 M solution of Acetic Acid. The Ka of HOAc is 1.8
x10-5
[H3O+]/(0.50-0.00095)=1.8x10-5 where did they get the .00095,
its said to take that as the second assumption
[H3O+]=9.4x10-4
[H3O+]/(0.50-0.00094)=1.85x10-5
[H3O+]=9.4x10-4 (this is said to be the third assumption)
Please, please help I really dont understand this, please show
all steps and be as descriptive as possible.
Calculate the pH of each solution.
A. A solution containing 0.0133 M maleic acid and 0.0189 M
disodium maleate. The Ka values for maleic acid are 1.20×10−2 (Ka1)
and 5.37×10−7 (Ka2).
B. A solution containing 0.0368 M succinic acid and 0.022 M
potassium hydrogen succinate. The Ka values for succinic acid are
6.21×10−5 (Ka1) and 2.31×10−6 (Ka2).
