- What are the advantages of potentiometric titrations over conventional titrations?Titration is the addition of a chemically equivalent volume of a solution of known concentration called analyte titrant fluent None of themIn a Li2CO3 solution, if it is not adequately filtered before titrations and solid remains, what type of error is created?
- The graphic below shows the general procedure for titrating the saturated solution of magnesium hydroxide with hydrochloric acid. Select all of the true statements from the choices below. 1. Obtain a saturated solution of magnesium hydroxide. 0 2. Transfer 30.0 mL to an Erlenmeyer flask using a volumetric pipet. Add phenolphthalein. 3. Titrate to a colorless endpoint using 0.0020 M hydrochloric acid. It is important that the aliquot drawn in step 2 does not contain undissolved magnesium hydroxide solid. For titrations of the saturated solutions at elevated temperatures, the solution must be held at high temperature for the duration of the titration. Hydrochloric acid is the analyte in this titration. The volume of liquid in the buret should be read before and after the titration. At the endpoint of the titration, the solution will turn from colorless to pink.4) The next 9 questions are related to the titration of 20.00 mL of a 0.0750 M acetic acid solution with 0.0700 M KOH. What is the volume of the solution at the equivalence point (in mL)? (This is the total volume, titrant added plus original volume of the analyt\ e solution) ((The answer is not 21.42 or 41))1- What are the differences between the direct and back titration
- 1. Do you always have to use a primary standard in the standardization of titrant? Why or why not?Which of the following is incorrect about direct titration? 1. OThe prepared solutions must be stable during titration 2. OStoichiometry of reaction between analyte and titrant should be known. 3. OReaction between titrant and analyte should be slow. 4. OReaction between titrant and analyte should be fast.It is a solution of unknown concentration in which a solution of accurately known concentration is gradually added until the reaction is complete.
