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.

2. After dissolving the KHP with water, a student noticed some undissolved solid, but continued with the titration as instructed by the procedure. He titrated until the pink color persisted for 30 sec and recorded the volume of titrant required. Preparing for the second determination, he set the reaction solution aside and added some more NaOH to the buret. He was about to pour the reaction solution down the drain, so he could rinse and reuse the flask, when he saw that the pink color had disappeared! a) What happened? b) What can the student do to correct for this erTor and salvage this trial? How should the data sheet be modified to reflect this correction? 3. Another student began adding titrant to the acid solution, but stopped when she suddenly realized that she forgot to add the 3 drops of phenolphthalein. When she did, the solution immediately turned dark red! a) What happened? b) What can the student do to correct for this error and salvage this trial? How should the data sheet…

Show all calculations clearly. A student dissolves 0.326 g of a powdered antacid in 32.36 mL of 0.1034 M HCI. The student boils the mixture and then allows it to cool. Finally, the student adds bromophenol blue indicator to the mixture, which turns yellow. 1. Calculate the total number of moles of HCI added to the antacid. 2. Boiling the mixture helps get rid of dissolved CO2. What is the source of most of this CO2? 3. Suppose that 11.72 mL of 0.1506 M NaOH is required to turn the solution from yellow to blue. Calculate the total moles of OH added. 4. Calculate the difference between the total moles of HCI added and the total moles of NaOH added. 5. How many moles of HCI reacted with the antacid? How many equivalents of antacid are present in the sample? 6. Find the number of equivalents of antacid present per gram of antacid. Note that the number of moles of HCl that react with the antacid equals the number of equivalents of antacid present. 7. Given that the antacid costs $5.99 per…
a) Compare between equivalence point and endpoint. Distinguish which point comes first. b) James performed an acid base titration experiment. A 25 mL sample containing HCl was transferred to Erlenmeyer flask using volumetric pipette. HCl sample was titrated against standardized 0.5010 M NaOH. An average titre volume of 24.35 mL was reported. Suggest a suitable pH indicator for James to be used in this experiment. Predict the initial concentration of the HCl. c) Alan and friends wish to sketch a weak acid strong base titration curve. Before they can do so, they need some data points.
