In order for all of the analyte to be consumed completely, an excess of a reagent has to be added. If 10.00 mL of a 0.1000 M HCl is needed in the back titration, what volume of a 0.5000 M NaOH should be added to a sample that contains 2.000 mmol of aspirin

What volume in mL of 0.1312 M NAOH is required to titrate 15.00 mL of 0.1021 M acetic acid (HAc)? mL

A 37.0 mL aliquot of a 0.600 M stock solution must be diluted to 0.100 M. Assuming the volumes are additive, how much water should be added?   How many milliliters of 11.0 M HCl(aq) are needed to prepare 675.0 mL of 1.00 M HCl(aq)?

4. A student did not read the directions to the experiment properly and mixed up where to put the NaOH and the HCl solutions. He put the HCl in the buret and the NaOH in the flask. He then added a drop of the phenolphthalein to the solution in the flask. Does the student need to empty out all of the solutions and start over again or can he go ahead and run the titration?

An analytical chemist weighs out 0.185 g of an unknown monoprotic acid into a 250 mL volumetric flask and dilutes to the mark with distilled water. She then titrates this solution with 0.2000 M NAOH solution. When the titration reaches the equivalence point, the chemist finds she has added 9.5 mL of NaOH solution. Calculate the molar mass of the unknown acid. Be sure your answer has the correct number of significant digits. g x10 mol

The following solutions are needed to be prepared for the titration procedure:1. 20 mL of 2 M HCl2. 20 mL of 0.05 M KOHYou went through the titration process wherein 1.0867 grams of Fe(OH)n was mixed with the 20 mL of 2 M HCl that you initially prepared. This solution was diluted to 200 mL and was labeled as solution A. 20.0 mL aliquot of solution A was taken and titrated with 20.0 mL of 0.05 M KOH.Submit a detailed procedure of what you had done the above titration (include all the laboratory apparatus that you used).

A science teacher needs to determine the concentration of an old, unmarked bottle of hydrochloric acid. She prepares a base titrant by dissolving 40.0 g of potassium hydroxide in 500.0 mL of water. The base is pipetted into a 28.00 mL sample of the acid, which also contains phenolphthalein as an indicator. The solution turns from clear to pink after the addition of 7.34 mL of base. What is the concentration of the hydrochloric acid?

3. A 4.912-g sample of a petroleum product was burned in a tube furnace, and the SO2 produced was collected in 3% H₂O₂. Reaction: SO2(g) + H₂O2 → H₂SO4. A 25.00-mL portion of 0.00873 M NaOH was introduced into the solution of H₂SO4, following which the excess base was back-titrated with 15.17 mL of 0.01102 M HCI. Calculate the sulfur concentration in the sample in parts per million.

In a lab, you diluted a sample of bleach to 1/10 concentration in a 250 volumetric flask. Then quantitatively transferred 25 ml of the 1/10 concentration diluted bleach into a beaker and titrated it with a standard sodium thiosulfate solution that has a molarity of 0.1215M. You repeated this 3 times. The data below is the amount of sodium thiosulfate that was titrated in the 3 runs. Calculate the molarity in each run of the diluted bleach and the concentration of undiluted bleach sample. Titration 1: 45.55 ml Titration 2: 45.67 ml Titration 6: 45.58 ml

A 185.0 mL sample of 1.200 M Pb(NO₃)₂ is mixed with 52.50 mL of 1.500 M NaCl, and the PbCl₂ precipitate is filtered from the solution. Then 200.0 mL of 3.000 M NaBr is added to the remaining solution, and the PbBr₂ precipitate is also collected and dried. What is the mass (in grams) of the PbBr₂ precipitate, assuming the yield in each precipitation step is 100%?
