QUESTION 8
25 mL of 0.1 M acetic acid are titrated with 0.05 M NaOH. At the
equilibrium point of titration, sodium acetate is hydrolyzed by
water:
CH3COO-(aq) + H2O(l) ->
CH3COOH(aq) + OH-(aq)
Calculate the concentration of hydroxide ions, OH-,
and the pH at the equilibrium.
Ka(CH3COOH) = 1.8 x 10-5.
25.00 mL of 0.1 M acetic acid are titrated with 0.05 M NaOH.
Calculate the pH of the solution after addition of 50 mL of NaOH.
Ka(CH3COOH) = 1.8 x 10-5.
0.1 M NaOH is titrated with 25 mL acetic acid. The equivalence
point was reached at 23.25 mL.
a) Based on your experimentally observed equivalence point of
23.25 mL, calculate the original concentration of the acetic acid
that came from the stock bottle.
b) Based on your experimentally observed half equivalence point
of 11.625 mL pH= 4.8, calculate the Ka of acetic acid.
c) Based on your answers to 1& 2 calculate the expected pH
at the equivalence point
a 22.5 ml sample of an acetic acid solution is titrated with a
0.175 M NaOH solution. The equivalence point is reached when 37.5
ml of the base is added. What was the concentration of acetic acid
in the original 22.5 ml? what is the ph of the equivalence point?
(ka (acetic acid) = 1.75 x 10^-5)
imagine mixing 25.0 ml of 0.10 M acetic acid (Ka=1.8*10^-5) with
25.0 ml of 0.10 M sodium acetate and determine a) The initial pH of
the buffer b) pH of 20.0 ml sample of buffer with 1.0 ml of 0.10M
Hal added c) pH of another 20 mL sample of buffer with 1.0 ml of
0.10 M MaOH added
For the titration of 75 mL of 0.10 M acetic acid with 0.10 M
NaOH, calculate the pH. For acetic acid, HC2H3O2, Ka = 1.8 x 10-5.
(a) before the addition of any NaOH solution. (b) after 25 mL of
the base has been added. (c) after half of the HC2H3O2 has been
neutralized. (d) at the equivalence point.
Consider the titration of 10.00 mL of 0.10 M acetic acid
(CH3COOH) with 0.10 M NaOH
a. What salt is formed during this reaction?
b. do you expect the salt solution at the equivalence point to
be acidic, neutral, or basic?
Calculate the pH of this solution at the equicalence point.
