How will you prepare the following solutions from 6.0 M solution of acetic acid? Give exact details. Assume that a 10-mL graduated cylinder (in which volumes can be read to the nearest 0.1 mL) and a 100-mL graduated cylinder are available.
80 mL of 0.10 M HC2H3O2
Given that vinegar is 5% acetic acid by weight, estimate the percentage of vinegar in the foods. Assume that vinegar is 1.05 g/ml.
Write a balanced chemical equation for the neutralization reaction upon which this titration is based, and indicate clearly which atom is being protonated. Then, calculate the equilibrium constant for the neutralization reaction.
