find the molarity of the acid or base solution. 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

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

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.
