- What happens when a non-standard titrant is used in the titration of an unknown sample?a - The volume of the acid used will not be accurate.b - The normality of the acid used will not be accurate.c - The weight of the analyte will not be accurate.d - It will not matter.You want to determine the concentration of NaCl in a water. In preliminary analysis, it appears to be saline water with a NaCl content of approximately 4%. Should you dilute the sample if your titrant has a concentration of 0.1 M and you want to spend 25 mL of sample? Solution: You must dilute approximately ten times, taking 10 mL of sample and making up to 100 mL. In this way, 17.20 mL of titrant will be spent.3. Why does adding a salt solution cause soap to precipitate?
- Hello, I'm having issue with this question: "Set up the factor label (dimensional analysis) calculation required to determine the concentration of the NaOH solution via titration of a given amount of KHP. Include all numbers except the given mass of KHP. Use “Mass of KHP” in place of your given mass" I started by converting the mass of KHP to moles, but I'm going wrong somewhere and not getting a correct answer because I think I'm missing numbers somewhere, but I'm not entirely sure. A picture of the titration I'm working from is also attached.In the titration calculation, moles of KOH were calculated from the known molarity and measured volume. Reaction stoichiometry was then used to convert that to moles of succinic acid. At this point, how could the moles of succinic acid be converted to a mass of succinic acid rather than a concentration?B. Determining the Composition of a Mixture of Sodium Chloride and Sodium Nitrate Partner I Prepare a solution of sodium chloride + sodium nitrate and indicator. Obtain a dropper bottle of potassium chromate (indicator) solution. To a clean and dry 125 mL Erlenmeyer flask, add about 40 mL of water and 8 drops of indicator solution. Weigh out approximately 0.05 grams of sodium chloride + sodium nitrate solid and record its exact mass. Dissolve the solid in the solution from step 1, stirring with a stirring rod to ensure complete dissolution. Determine and record the total mass of the Erlenmeyer flask and solution, noting the balance that you use to weigh. Rather than measuring the volume of silver nitrate solution added as in Part A, we will measure the mass of titrant added and make use of the weight-percentage concentration of silver nitrate in calculations. Prepare the silver nitrate solution. Obtain about 15 mL of 1.70% w/w silver nitrate solution in a 50 mL beaker. Designate a…
- Volumetric Analysis: Determination of Acetic Acid in Vinegar The endpoint of the titration of the vinegar sample is overshot! How will this technique error affect the calculated percent acetic acid in the vinegar?Volumetric Analysis Liza carefully pipets 25.0 mL of 0.525 M NaOH into a test tube. She places the test tube into a small beaker to keep it from spilling and then pipets 75.0 mL of 0.355 M HCl into another test tube. When Liza reaches to put this test tube of acid into the beaker along with test tube of base, she accidentally knocks the test tubes together hard enough to break them and their respective contents combine in the bottom of the beaker. Is the solution formed from the contents of the two test tubes acidic or basic? What is the pH of the resulting solution?explain why the volume of water did not need to be exactly measure or recorded in Titration?
- The following volumes of 0.000300 M SCN- are diluted to 15.00 mL. Determine the concentration of SCN- in each sample after dilution. These values will be used during the experiment. Sample 0.000300 M SCN- (mL) [SCN-] (M) 1 1.50 2 3.50 3 7.00 4 10.00What is volumetric analysis and its components such as titrant, titrand, analyte, base, solution,known and unknown concentrations etc. Explain in a simple way.For an experiment, I titrated NaOH with an unknown sample that had acetylsalicylic acid. In my few trials I found the average concentration and moles for the NaOH and asked to find the mass of acetylsalicylic acid in the sample I measured. How do I do that?
