A student was conducting a titration experiment and was asked to calculate the theoretical pH of the solution at various points in the titration curve. In this experiment, the student added 47.812 ml of a 2.765M solution of acetic acid to a 200ml beaker. The student then added 92.1 ml of deionized water and began to stir. Calculate the theoretical pH at the following. Initial pH before addition of any NaOH? Be sure to consider the change in volume due...
In the titration of 100 ml of a 0.1 M H3PO4 with 0.5 M NAOH, calculate the pH of the solution at each of the following points: A) before any NaOH added B) After 10 mL of NaOH added C) at 1st equivalence point
Calculating Ka from titration curve. We titrated H3PO4 with NaOH. We began with 40.0 mL 0.0970 MH3PO4, titrated with 0.2085 M NaOH. We reached first equivalence at 18.78 mL NaOH titrated, and second equivalence at 38.50 mL titrated. Calculate Ka1 for H3PO4 using the following data obtained from a titration curve: 1) From the initial pH = 1.97 2) From the pH value half way to the first equivalence point = 2.10 Calculate Ka2 for H3PO4 from the following data...

Consider the titration of 50.0 mL of 0.200 M hypochlorous acid HCIO (Ka = 3.5 x 10-8) with 0.250 M NaOH. 5- How many milliliters of NaOH are required to reach the equivalence point? a) b) Calculate the pH before titration c) Calculate the pH after adding 40.0 mL. of NaOH d) Calculate the pOH after adding 20.0 ml, of NaOH
For a titration experiment: I am using 1.025 M of NaOH(aq) as my titrant. My titration solution is 4.0 g of potassium hydrogen tartrate, with 300 mL of distilled water. After 4 trials, my average NaOH used was 1.680 mL. I am having problems figuring out how to calculate my findings. Each trial started with 50 mL of potassium hydrogen tartrate solution, and 2 drops of phenophthalein. Then I added 1.680 mL of NaOH (on average) to get titration to...

Calculate the pH at 0, 10.0, 25.0, 50.0, and 60.0 mL of titrant in the titration of 25.0 mL of 0.200 M HA with 0.100 M NaOH. Ka = 2.0 x 10-5.
In a strong base/weak acid titration: titrant: NaOH analyte: H3PO4 solution There should be three equivalence points since there are three protons transferred...why does my titration curve only show two?
A titration is performed on 50mL of a 0.10 M solution of HN3 (Ka+1.9x10-5) with 0.10 M NaOH as the titrant. (a) What is the initial pH of the HN3 solution? (b) Calculate the pH of the solution after 25 ml of NaOH have been added (c) How many mL of NaOH are required to reach the equivalence point and what is the pH of the solution at the equivalence point.
