- Include relevant qualitative test(s) in your explanation in the separation of benzoic acid from NaCl in aqueous solutionHow would you use an experimentally determined Ksp value to calculate that Ag2CrO4 should precipitate when 5ml of 0.0040 M AgNO3 are added to 5ml of 0.0024 M K2CrO4. You can come up with your own experimentally Ksp value. I just want to see steps in solvingAs a chemist, you know that when analyzing a 50-ml sample for total hardness, every milliliter (1.00 mL) of EDTA titrant removes an equivalent of 20 ppm CaCO3. What would be the total hardness of a sample if a total of 24.57 mL titrant was used? Based on the preceding question, if 0.25 mL was used in the blank titration to achieve the same end-point color, what will be the correct total hardness of the sample?
- In this experiment, it was necessary to assume that [FesCN^ 2+ ] std was equal to [SCNJinitial. Explain how the use of a relatively huge amount of Fe^ 3+ allowed us to make this assumption. Include the application of Le Chatelier's principle in your answer.A 35 year old male was taken to the hospital with excruciating pain in the lower abdominal area. It was discovered that this patient drank no more than half a glass of water each day over the past week, while drinking at least three cups of black tea on the same days. Additionally, the patient regularly eats very large quantities of spinach. Upon further analysis, it was determined that the presence of Calcium Iodideand Sodium Oxalate may have led to the pain that the patient was experiencing. Determine whether or not kidney stones could be the probable cause of the lower abdominal pain for this patient by answering the following questions (Be sure to show your work for all parts): Assume that Calcium Iodideand Sodium Oxalate are the starting substances (reactants) in the reaction: a. Write a balanced chemical equation describing the formation of kidney stones, using the information in the case study. b. State the names of the products that are produced from this reaction. c.…A 35 year old male was taken to the hospital with excruciating pain in the lower abdominal area.

However,Tom suspected that he might have received regular coffee and therefore decided to analyze hiscoffee for caffeine. In the lab, he took 0.5 mL of the brewed coffee and diluted it in water tomake a 100.0 mL solution. He performed four analyses and found the concentrations to be 4.69,3.99, 4.12, and 4.50 mg/L, respectively. (Assume the density of all solutions is 1.000 g/mL,1oz= 28.35 mL).(a) Report the concentration (in mg/L) of caffeine in the brewed coffee using the format asaverage ± standard deviation. (Note this is not the concentration in the diluted solution.)(b) Look up the caffeine content of regular vs. decaffeinated coffee. Do you think that Tom wasgiven the wrong type of coffee?(c) Caffeine intake of 300 mg per day reportedly has no adverse effects in the vast majority ofthe adult population.
