- Your lab assignment presentation involves putting together a presentation to show other students on how to perform titration. In other words, your presentation can be used to show other students (next term) how they can perform a titration by following your instructions and calculations. To do this presentation, we are giving you the type of acid, acetic acid, the type of base, NaOH to be used, and you will use phenolphthalein as the indicator. You will use the data given to you to be used as an example of how to solve the mathematical calculations. At the end of your presentation, you will show the unknown concentration of the acetic acid (Molarity) and will also show the % mass/ vol of the Vinegar solution. Part 1 Purpose of a titration, what is titration and why do we perform a titration? Instrumentation- what are the instruments, glassware used when performing a titration. Chemicals and Procedures. What chemicals are needed? List and explain the procedures for this experiment.…A student performed titration to find the concentration of acetic acid. Titrant was sodium hydroxide. He went beyond the indicator color change by adding too much titrant. How will his experimental error affect the calculated value for the concentration of unknown acetic acid? calculated value actual value. calculated value < actual value calculated value = actual value. more information is necessary this is not a source of errorWill 260 milligrams of calcium carbonate raise the pH of 75.0 milliliters of stomach fluid from a low pH of 1.0 into the normal pH range of 1.5-3.5? The first step of this problem is to convert 260.0mg of calcium carbonate to grams of calcium carbonate. Submit a reply that that tells how you decide approach the problem and shows the work that results in an answer. Use correct units and significant figures. In addition, reply to another student's a
- Consider the titration of 25.00 mL of Sprite with 0.053 M NaOH. Using the following data, determine the citric acid concentration in Sprite (g/L). Take the molar mass of citric acid to be 192.124 g/mol. Give your answer to one decimal place. initial volume (mL) final volume (mL) Your Answer: Answer Buret reading (mL) 1.64 14.52Hello, 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.If your first titration yielded a concentration of 0.37 mg/mL and your second titration yielded a concentration of 0.6 mg/mL, what was the average concentration for your two titrations (in mg/mL)? Include the unit and two decimal places in your answer.
- Before performing a titration of vinegar itself, you first had to standardize the solution used to analyze vinegar. State the name (an abbreviation is fine) of the compound used standardize the test solution and explain why that compound was selected for use in standardization.Try Again Your answer is incorrect. ● HF: Your answer is incorrect. Some chemical compounds are listed in the first column of the table below. Each compound is soluble in water. Imagine that a few tenths of a mole of each compound is dissolved in a liter of water. The important chemical species that would be present in this solution are written in the second column of the table. Use the checkboxes to classify each compound. compound НІ HF NH3 NaI important species present when dissolved in water H₂O, I, H₂O H₂O¹, F, HF, H₂0 + NH,, OH ,NH,,H,O + Na, I, H₂O type of compound (check all that apply) strong weak strong weak acid acid base base ionic molecular U U 0 U 0 0 0 0A student did not read the directions to the experiment properly and mixed up where to place the NaOH solution and the vinegar. He put the vinegar in the titrator and the measured amount of NaOH in the beaker. He then added a drop of the phenolphthalein to the solution in the beaker. Does the student need to empty out all of the solutions and start over again or can he go ahead and run the titration? If he runs the titration using the solutions as given above, what should he expect to see happen for results?
- 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.Review I Constants Periodic Table A buffer is prepared by adding 18.0 g of sodium acetate (CH3 COONA) to 490 mL of a 0.155 M acetic acid (CH3 COOH) solution.
