www.ux1.eiu.educ) Find the Ka value of acetic acid from the titration curve – Figure 2A. Show how this was done. (Hint: Use the buffer region of the titration curve). 3. For the weak diprotic acid/strong base titration: a) Find the concentration of the maleic acid solution using data from one of the titration curves. Show your calculation.
Determination of an Unknown Diprotic Acid by Titration Dr ...
facultystaff.richmond.eduToday you’re going to do your second titration experiment of the semester. In the first titration experiment you used an indicator to find the endpoint – the point at which your original solution, either HCl or NaOH, was completely reacted. In this experiment we’re going to do a titration of a weak diprotic acid (an unknown) by a
Experiment 6 Titration II – Acid Dissociation Constant
chemistry.uccs.eduA titration curve for a triprotic acid is thus expected to have three equivalence points, but often only shows two. A titration curve for a diprotic acid, H2A, would show two equivalence points, one in which OH− neutralizes H 2A and a second in which OH − …

www.fountainheadpress.comIn this lab you will perform a pH titration to determine if an unknown acid is monoprotic or diprotic, and to determine the Ka value(s) for the acid. You will then perform replicate indicator titrations and calculate the molar mass of the unknown acid using Equation (8).
DETERMINING THE CONCENTRATION OF CITRIC ACID IN A …
www.webpages.uidaho.eduAcids can be classified as monoprotic, diprotic, triprotic, etc.: a monoprotic acid has one proton that can undergo a reaction with a base, a diprotic acid has two such protons, and a triprotic acid has three. Shown below are examples of each type of acid undergoing a reaction with sodium hydroxide.
Ch. 10: Acid-Base Titrations
chem320.cs.uwindsor.caTitration: Weak Acid with Strong Base We will consider the titration of 50.00 mL of 0.02000 M MES with 0.1000 M NaOH. MES is an abbreviation for 2-(N-morpholino)ethanesulfonic acid, which is a weak acid with pKa = 6.27. This the reverse of the Kb reaction for the base A−.Therefore, the equilibrium constant for is K = 1/Kb = 1/(Kw/Ka (for HA)) = 5.4 × 107.

To solve these problems, use M1V1 = M2V2. 1) 0.043 M HCl 2) 0.0036 M NaOH For problem 3, you need to divide your final answer by two, because H2SO4 is a diprotic acid, meaning that there are two acidic hydrogens that need to be neutralized during the titration. As a result, it takes
