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...
please explain steps 1. Calculate the volume of glacial acetic acid (17.6 M) and mass of sodium acetate (mm-82.03) required to make 102 ml of 0.20 M buffer at pH 4.85. The Ka of acetic acid is 1.4 x10. (this question is challenging, use the background section and your book for help). 2. Consult the table of Ka values in the back of your textbook and suggest acid/conjugate base system (mono-protic acid only) that would yield a strong buffer capacity...
You will be using a mixture of 5:1:4 volume ratio of butanol, glacial acetic acid (pure acetic acid), and water in this lab. Assume that butanol is the same as water in terms of a pH calculation. The density of acetic acid is 1.05 g/ml. The molecular weight of acetic acid is 60.05 g/mol. The Ka of acetic acid HAc is 1.8*10^-5. You can make the assumption that [H+] = [Ac-] << [HAc] here. What is the pH of this...

Use the data to inform your procedure. % Mass #DIV/0! Name 9 M NaOH Density (g/mL) 0.5167 1.002 Trial 1 Trial 2...
Glacial acetic acid is 99.5% acetic acid (f.w. 60.052) by weight and has a density of 1.05g/mL. Calculate the volume of glacial acetic acid needed to make 1L of the 0.100M pH 5.000 buffer.
molarity of acid: 0.1435M volume:25ml 1. Use the molar mass and moles of acetic acid to determine the mass of the acetic acid in the 25.00-ml sample. 2. Calculate the mass/volume percentage (m/v %) by dividing the mass of acetic acid in grams by the volume of the vinegar sample in mL and multiplying by 100. 3. For the reaction of sodium hydroxide solution with a solution of hydrochloric acid: a. Write a balanced molecular equation for the reaction, including...
