Answer #1

The titration curve of a weak acid is the plot between pH values and the volume of base added to neutralize the acid. pH values are kept at y axis and volume of base added is kept at x axis. The titration curve of a weak acid when treated with strong base is shown below:-

The equivalence point is above pH 7 due to the formation of salt of a weak acid and strong base.

Given that:- The ratio of salt to acid = 3:1

Using henderson hasselbalch equation to calculate the pH of a acidic buffer. The pKa of weak acid is 3.2.

Applying the values in the above equation as:-

The pH value is shown in the image below:-

Draw a titration curve that shows how the pH of a diprotic acid changes as 30 mL total of NaOH is added. Label both equivalence points and half equivalence points, including their associated volumes on the x-axis. You should also label pH values on the y-axis that are associated with the half-equivalence volumes.

I need to find the pKa and Ka value of CH3COOH for my Acid-Base titration experiment. It’s pH before titration is 2.37 pH at equivalence point is 9.17 [H3O+] before titration is .00427 [H3O+] at equivalence point is 0.99 (Don’t know if it’s needed but the midpoint on the titration curve is (5.5ml, 7.49ph) . . Step by step explanation would be helpful!
