Acid-base Titration Curve Calculations (Strong Monoprotic Acid-Strong Base) Key Concepts. (iii) Write the equation for the second reaction marked on the curve. neutralize, pH, strong acid, strong base, titrant, titration, titration curve, weak acid, weak base Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1)C The most common approach for the calculation of titration curves is based on approximations depending on the relative strength of the Titration Curves. For the preparation of a titration curve of an acid-base titration, the base is added in small increments and the pH of the acid in each step is determined with a pH meter. Explain what that means. When the titrant is a strong ... the report is more than just answering some questions and that it should flow smoothly and logically as you discuss the data obtained, what it signifies, and potential errors or difficulties. Choose the one alternative that best completes the statement or answers the question. C = NH 4 +. In simple terms, the titration curve is the plot of pH of the analyte (titrand) versus the volume of the titrant added as the titration progresses. The titration curve above was obtained. 15. A titration curve is a graph of pH vs. the volume of titrant added. Figure %: Titration of ammonia with hydrochloric acid A = NH 3, it has yet to be acidified. In answering questions 15-19, consider the following titration curve. www.chemguide.co.uk The Ka of the monoprotic acid is about _____. A solution of 0.100 M HCl and a solution of 0.100 M NaOH are prepared.A 40.0 mL sample of one of the solutions is added to a beaker and then titrated with the other solution. A titration curve is a graph that relates the change in pH of an acidic or basic solution to the volume of added titrant. c) The titration curve for running sodium hydroxide solution into ethanedioic acid (oxalic acid) solution looks like this: (i) Ethanedioic acid is a diprotic acid. The pH of the solution at the equivalence point may be greater than, equal to, or less than 7.00. Answer Key Testname: QUIZ_TITRATION_CH_15.TST MULTIPLE CHOICE. Which one of the following combinations does the titration curve represent? A strong acid will neutralise a strong base in a neutralisation reaction: H + (aq) + OH-(aq) → H 2 O (l) or H 3 O + (aq) + OH-(aq) → 2H 2 O (l) In an acid-base titration, a known volume of one reactant is placed in the conical (erlenmeyer) flask. Students are not expected to know the answers to the Prior Knowledge Questions.] The titration curve can be calculated theoretically, whereupon conclusion can be drawn from it for the feasibility and the expected accuracy of a titration, and the selection of the proper indicator. A Addition of a strong base to a weak acid B Addition of a weak base to a strong acid C Addition of a strong acid to a … List the major species at points A, B, C, and D on the following titration curve of the titration of ammonia with HCl. For acid-base titrations, solution pH is a useful property to monitor because it varies predictably with the solution composition and, therefore, may be used to monitor the titration’s progress and detect its … A pH electrode is used to obtain the data that are plotted in the titration curve shown above. Q. A)1 ˛ 10-2 B)1 ˛ 10-4 C)1 ˛ 10-6 D)1 ˛ 10-8 E)1 ˛ 10-12 A-1. B = NH 3 and NH 4 + in the buffering region. Which curve is produced by the addition of a 0.1 molL-1 strong acid to a 0.1 molL-1 weak base? (ii) Write the equation for the first reaction marked on the curve. The characteristics of the titration curve are dependent on the specific solutions being titrated. [Note: The purpose of these questions is to activate prior knowledge and get students thinking.
