What determines the taste of cheddar cheese? Experimenters assessed the concentration of lactic acid, acetic acid, and hydrogen sulfide in randomly chosen pieces of cheddar cheese that were also rated for taste by a panel of food tasters (the higher the score, the tastier). Data from the study are shown in the provided table, “Acetic” and are actually log‑transformed concentrations.

A food chemist determines the concentration of acetic acid in a sample of apple cider vinegar by acid-base titration. What is the concentration of acetic acid in the vinegar if the density of the sample is 1.01 g/ml, the titrant is 1.002M NaOH and the average volume of titrant required to titrate 25.00 mL subsamples of the vinegar is 20.78mL? Express your answer the way a food chemist probably would; *as percent by mass*
A solution containing a mixture of lactic acid and lactate was found to have a pH of 3.56. Calculate the ratio of the lactate concentration to the lactic acid concentration in this solution.
During exercise when the body lacks an adequate supply of oxygen to support energy production, the pyruvate that is produced from the breakdown of glucose is converted into lactate. High lactate levels can lead to acidity in the muscle cells as some of the lactate hydrolyzes to lactic acid. The dissociation of lactic acid to lactate is shown in the reaction below. Lactic acid has a pKa of 3.86. A solution containing a mixture of lactic acid and lactate was found to...

In this lab, we will titrate NaOH into Binegar (acetic acid) to determine its concentration. These are the principle questions: - What is the reaction that occurs in this titration? - What does a titration measure, and how does it measure this quantity? - What is a titration curve? How would it differ for diprotic of triprotic acids? - What is an equivalence point? - How do you select an indicator?
