3. Household vinegar is an aqueous acetic acid solution. A particular sample of vinegar has a pH of 2.90. Assuming that the vinegar contains only acetic acid (CH3COOH), with a ki of 1.8 x 10-5 at this temperature, calculate the initial concentration of acetic acid in the vinegar in units of molarity.
chem 110 experiment 12 tritation vinegar need help fast please!!! The density of vinegar is 1.01 g/mL. How would this information affect your experimental results. 2. Weak acids, such as acetic acid, typically have an odor, whereas strong acids often do not. Explain this is so EXPERIMENT # 1 2 ACETIC ACID CONTENT OF VINEGAR Objectives Use chemical pll indicators to find endpoints of acid base titrations Use the burets to undertake chemical titrations PreLab questions i.

Calculate the moles of acetic acid, molarity of the vinegar solution, and mass %. of acetic acid in the vinegar using the average of three good trials used to titrate 5.00 mL of the vinegar. You may assume that the density of your vinegar sample is 1.01 g mL^-1. Drain off unused NaOH solution into a clean container and place it into a designated container. Wash the buret two times with regular tap water, then rinse with deionized water, and...
Answer both questions please Suppose a sodium hydroxide solution is to be standardized against pure, solid, primary-standard grade KHP. If 0.4538 g of KHP requires 44.12 mL of the sodium hydroxide solution to reach a phenolphthalein endpoint, what is the molarity of the NaOH solution? Show your calculations. 5. If 36.32 mL of the NaOH solution described in question 4 was required to titrate a 5.00 mL sample of vinegar, calculate the molarity of acetic acid in the vinegar. Show...
I need it right now, please help me?? PROCEDURE PART I: DILUTING THE VINEGAR SOLUTION The vinegar solution must be diluted by a factor of 5 to be suitable for titration. 1. Obtain - 20 ml of the stock vinegar solution from the fume hood. 2. Using the 10-ml. pipet, pipet" 10 mL of the stock solution to a 50-ml volumetric flask. 3. Fill the volumetric flask to the calibration line with distilled water. Be sure not to go over...

Materials: NaOH MW = 40 g/mL, KHP - potassium hydrogen phthalate, KHC8H404, MW = 204.23 g/mol. Acetic acid, HC2H302, MW = 60.05 g/mol Part 1: Standardization of NaOH Assume 0.951 g of KHP is weighed and transferred to a 250 mL Erlenmeyer flask. Approximately 50 ml water is added to dissolve the KHP. Note that the exact volume of water is not important because you only need to know the exact number of moles of KHP that will react with...
