Titration Curve for Diprotic Weak AcidDavid T. HarveyDePauw University
Calculate the molar mass of a diprotic acid. It reaches the endpoint of the titration with NaOH at 28 ml. The initial concentration of NaOH is 0.09792 and the initial mass of the diprotic acid is 0.685 g. Molar Mass: T...
A state-of-the-art survey of the determination of acid dissociation microconstants of diprotic acids is presented. It is shown that potentiometric and spectrophotometric titration data can yield macroscopic constants but are not sufficient to completely resolve the microconstant system unless some sort ...
The titration of a 50.0 mL sample of diprotic acid required 23.6 mL of 0.100 M NaOH. What was the concentration of the acid? Given: Mass of diprotic acid sample 0.117 g Concentration of NaOH 0.0500 M What are the moles of diprotic acid, H_2X present? What is the...
i am studying the effect of an acid being mono/diprotic on order of reaction/reac tion rate.are di's more reactrive becasue more protons are available?what effect may this have on order of reaction with relation to the acid?Logged
1. How does the titration of a diprotic acid differ from a monoprotic acid (like HF)? 2. How does the titration of a weak base with a strong acid differ from weak acid-strong base titration. (Review Phosphoric acid...
A spreadsheet and chart, set up using Excel, for showing titration curves of any diprotic acid or base is described. Keywords (Audience): High School / Introductory ChemistryKeywords (Feature): Computer SeriesKeywords (Pedagogy): Computer-Based LearningKeywords (Subject): Acids / BasesG. L. ...
Visible color changes in the vivid, highly absorbing dye permit students to "see" relative amounts of acid, base, and ampholyte species during the titration, while potentiometric measurement of pH and spectroscopic determination of concentrations permit quantitation of the species present. A standard ...

A function involving pH and titrant volumeV (which is linearly dependent on V and becomes zero at the first equivalent point of titration of a weak diprotic base with a strong monoprotic acid) has been critically examined and validated by means of widely extended simulated experiments. Accurate...
