Write a balanced equation for the titration of NaOH with: Citric acid (acid in candy) Lactic acid (acid in milk) How would having a large air bubble in the buret tip at the start of the experiment affect the calculated value of g acid/g of sample? List 3 other substances that you can use (instead of Sweet Tarts or mil) to determine the amount of acid. Make sure that these substances contain different acid than lactic or citric acid. Substance Name of Acid Comparing whole milk, 2% milk and skim milk, which do you expect to have more acid and why?
