1. The pH of a solution made of 1.0 M acetic acid and 0.1 M
potassium acetate is (K_a = 1.8 x 10^-5) to which 0.001 mol of KOH
has been added: a) pH = 4.74 b) pH = 4.73 c) pH = 8.92 d) pH = 4.46
e) pH = 11.55 The answer is not 4.74!!
2. The pH of a solution made of 1.0 M acetic acid and 0.1 M
potassium acetate is (K_a = 1.8 x 10^-5)...
Need to prepare an acetate buffer solution: 25.00 mL of 0.1 M
acetic acid and 0.1 M sodium acetate. The stock acetic acid is 6.0
M. The instructions involve the preparation of a (10-fold)
intermediate acetic acid solution. Ka = 1.75 x
10-5 (pKa = 4.76). What are the values for the:
* volume of acetic acid
* grams of sodium acetate (since it's a solid)
* volume of DI water needed
* calculated pH
Thanks.
Calculate the pH of a solution of 0.25 M Acetic acid and 0.34M
Sodium acetate before and after 0.036 M NaOH is added to the
solution. Ka of HAc = 1.8 x 10 -5
Please Use the ICE method
What volumes of 0.1 M acetic acid, pKa 4.76,
and 0.1 M sodium acetate are required to make 1 L of acetate
buffer, pH 5.30?
776 mL acetate, 224 mL acetic acid
351 mL acetate, 649 mL acetic acid
540 mL acetate, 460 mL acetic acid
712 mL acetate, 288 mL acetic acid
Calculate pH at equivalence point when 100 mL of a 0.1 M
solution of acetic acid (HC2H3O2), which has a Ka value of 1.8 x
10^-5, is titrated with a 0.10 M NaOH solution?
Please show your ICE chart and why you chose to use the
equations you did.
In the solution containing both 0.10 M acetic acid and 0.10 M
sodium acetate, the acetic acid undergoes ionization. The chemical
equation for this ionization reaction is the same as for a solution
containing acetic acid alone. The difference is that the initial
concentration of acetate ion (before any ionization reaction
occurs) for the solution containing acetic acid alone is zero,
whereas the initial concentration of acetate ion is 0.10 M in your
solution containing both acetic acid and sodium...
An acetic acid/ sodium acetate buffer solution is also 0.020 M
AlCl3. At what minimum pH will Al(OH)3 (s) precipitate form this
solution? What ratio of acetate ion to acetic acid concentrations
([C2H3O2-]/[HC2H3O2]) should be maintained to prevent the
precipitation of aluminium hydroxide?
