The active ingredient in a certain toilet cleaner that claims to 'remove lime scale and rust' is hydrochloric acid of approximate concentration 10.9 mol/L. To analyze this toilet cleaner, a quality control chemist first delivered a 10-ml aliquot of the toilet cleaner into a 250-mL volumetric flask, then made up the diluted solution. She then titrated a 25 mL aliquot of this diluted solution against standard sodium hydroxide solution of concentration 0.46 mol/L. The expected titre (or volume of the titrant in mL) would be approximately:

A student measured 20 drops of vinegar and one drop of phenolphthalein solution into a well of her well plate. After she had added 35 drops of NaOH solution to the same well, the well was full, but she had still not reached the titration endpoint. She then took a clean pipet and transferred some of the titration mixture into a second well. She rinsed the pipet with a few drops of distilled water and transferred the rinse water into the titration mixture in the second well. Then she continued adding NaOH solution to both wells until she reached the endpoint in both wells. She then recorded the total number of drops of NaOH solution added to both wells and used it to calculate the data for her vinegar titration. Briefly comment on her procedure and the accuracy of her results.
You have been provided with a 32.5ml sample of hydrochloride acid (HCl) of unknown concentration. You perform a titration with 1.50M sodium hydroxide (NaOH), and find that 3.75 x 10^-2 L are required to reach the equivalence point (as determined using a coloured indicator) what is the concentration of the hydrochloride acid solution in mol L^-1? To the correct number of significant figures.

The active ingredient in a certain toilet cleaner that claims to ‘remove lime scale and rust’ is hydrochloric acid of approximate concentration 11.6 mol/L. To analyze this toilet cleaner, a quality control chemist first delivered a 10-mL aliquot of the toilet cleaner into a 250-mL volumetric flask, then made up the diluted solution. She then titrated a 27 mL aliquot of this diluted solution against standard sodium hydroxide solution of concentration 0.1705 mol/L. The expected titre (or volume of the titrant in mL) would be approximately:
H2. Titrations are performed by a scientist in the laboratory as follows: a solution of deuterated hydrochloric acid contains 1.08 g DCl in 750 ml of deionised, distilled water. An average amount of 14.95 ml of the DCl(aq) solution is titrated with 25.0 ml of Ca(OH)2 to produce an endpoint (as determined by an appropriate indicator). What is the molarity of the Ca(OH)2 solution? You must include all of your calculations Please give typed answer
Iodometry is a standard method for redox titration. In many indirect methods one lets the analyte (the substance whose concentration is to be determined) react with iodide ions as then forms triiodide ions, I3- . The amount of triiodide ions is then determined by titration with thiosulphate ions, S2O32- which then form tetrathionate ions, S4O62- whereby the triiodide ions change into iodide ions. Determine the mass of triiodide ions in a solution from the following data. The sample containing triiodide ions was titrated with a 0.01002 M sodium thiosulfate solution of which 18.38 mL were required.
A chemistry student needs to standardize a fresh solution of sodium hydroxide. She carefully weighs out 316.mg of oxalic acid H2C2O4 , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in 250.mL of distilled water. The student then titrates the oxalic acid solution with her sodium hydroxide solution. When the titration reaches the equivalence point, the student finds she has used 93.2mL of sodium hydroxide solution. Calculate the molarity of the student's sodium hydroxide solution. Be sure your answer has the correct number of significant digits.
To determine the fluoride content in an aqueous and chloride-containing preparation of ammonium fluoride, the following analysis was performed. 105.2 mg of the preparation was dissolved in 100.0 mL of water. Then a 300 mL 40 mM lead chloride solution was added, whereby all fluoride ions were precipitated out of the solution in the form of the sparingly soluble salt PbClF (s). The precipitate was separated and washed at 15 degrees with a lead fluoride chloride saturated solution and dried at 130 degrees. The precipitate weighed 651.3 mg. a) Calculate the fluoride content (as % by weight F) in the preparation.b) Determine the purity of the ammonium fluoride preparation
A chemistry student needs to standardize a fresh solution of sodium hydroxide.
