A chemist needs to determine the concentration of a sulfuric acid solution by titration with a standard sodium hydroxide solution. He has a 0.1494 M standard sodium hydroxide solution. He takes a 25.00 mL sample of the original acid solution and dilutes it to 250.0 mL. Then, he takes a 10.00 mL sample of the dilute acid solution and titrates it with the standard solution. The endpoint was reached after the addition of 18.48 mL of the standard solution. What...

1. A student carries out a back titration to determine the concentration of ammonium chloride in a solution. The student collects 10.80 mL of the original NH4Cl solution and dilutes it to 250.0 mL (we will refer to this as the dilute NH4Cl solution). Then 25.00 mL of the dilute NH4Cl solution are transferred to an Erlenmeyer flask and 25.00 mL of 0.1963 M NaOH are added. Calculate the moles of NaOH added to this Erlenmeyer flask. 2. In the...

11. To determine the concentration of a solution of sulfuric acid, a chemist titrates the solution with aqueous potassium hydroxide. She finds that 21.4 mL of 2.50 M aq. KOH is required to neutralize 10.0 mL of aq, HSO a. Write the balanced equation for this neutralization reaction b. What was the concentration of the H2SO4 solution?

To determine the concentration of a solution of sulfuric acid, a 125.0-mL sample is placed in a flask and titrated with a 0.1433 M solution of cesium hydroxide. A volume of 20.29 mL is required to reach the phenolphthalein endpoint. Calculate the concentration of sulfuric acid in the original sample. A student has 530.0 mL of a 0.1474 M aqueous solution of MnSO4 to use in an experiment. He accidentally leaves the container uncovered and comes back the next week...

7. A laboratory needs to find out the concentration of a solution of nitrous acid (HNO2, a monoprotic acid). The laboratory technician uses a procedure just like you will use in this laboratory activity. In Part l, the technician titrates the barium hydroxide solution against a standard, solid acid. It is found that the barium hydroxide solution is 0.198 M in barium hydroxide In Part Il, the technician places a 25.00 ml sample of the nitrous acid solution in an...

Answer the following questions for titration of 10.00 mL of a hypochlorous acid solution with a 0.09975 M sodium hydroxide. 1. If 20.05 mL of the sodium hydroxide solution were required to reach the endpoint in the titration, what was the original concentration of the hypochlorous acid solution? 2. What was the initial pH of the hypochlorous acid solution (before any sodium hydroxide was added)? 3. What was the pH in the titration after addition of 4.01 mL of NaOH?...

• Titration calculations: • A chemist titrates 30.00 mL of 0.200 M acetic acid with 0.100 M sodium hydroxide. Calculate the pH at the four titration points described below. • If needed, use k, = 1.7x10-5 for acetic acid. 1. Before any sodium hydroxide is added. 2. After adding 25.00 mL of sodium hydroxide. 3. After adding 60.00 mL of sodium hydroxide. 4. After adding 75.00 mL of sodium hydroxide.

A chemist needs to create a series of standard Cu2+ (aq) solutions for an absorbance experiment. For the first standard, he uses a pipet to transfer 10.00 mL of a 2.68 M Cu2+ (aq) stock solution to a 250.0 mL volumetric flask, and he adds enough water to dilute to the mark. He then uses a second pipet to transfer 10.00 mL of the second solution to a 50.00 mL volumetric flask, and he adds enough water to dilute to...
