Weak Base - Strong Acid Titration:
when the weak acid-strong base titration = crotonic acid, C4H6O2, ka=2.04 times 10^-5.
and when the value salt of weak acid (Buffer) is Na^+C4H502^-
A 40.0 mL sample of 0.30 mol/L of your weak base is titrated with a 0. 60 mol/L solution of
HCl(aq), calculate the PH of the solution:
Give an answer for all the part a,b,c,d:
a) before titration begins
b) after 10.0 mL of HCl(aq) has been added.
c) At the equivalence point
d) Draw the PH curve for the titration, label the axes and the equivalence point.
Buffer:
A buffer solution is prepared by dissolving 100.0 gram of the weak base and 100.0 gram of its salt
in 1. OL of water. Determine the PH:
Make sure to answer all the part e,f,g:
e) of the buffer
f) after 0. 10 mol HCI was added to the initial buffer (assume volume remains 1. OL)
g) after 0. 12 mol NaOH was added to the initial buffer (assume volume remains 1. OL)
