Chapter 2, Problem 41P

Name the major organic compound formed by the following reaction: ОН KMnO4

Explain why the pH of a 0.25 M solution of formic acid (HCO2H) has a lower pH than a solution that is 0.25 M in both formic acid and sodium formate (NaCO2H). Please include chemical reactions.

The amount of tartaric acid is responsible for the tartness of wine and controls the acidity of the wine.  Tartaric acid also plays a very significant role in the overall taste, feel and color of a wine.   Tartaric acid is a diprotic organic acid The chemical formula for tartaric acid is C4H6O6 and its structural formula is HO2CCH(OH)CH(OH)CO2H.   A 50.00 mL sample of a white dinner wine required 21.48 mL of 0.03776 M NaOH to achieve a faint pink color.  Express the acidity of the wine in terms of grams of tartaric acid, H2C4H4O6 (M. M.  =  150.10) per 100 mL of wine.  Assume that the two acidic hydrogens are titrated at the end point. MM H2C4H4O6 = 150.10 MM NaOH = 40.00 Below is the balanced chemical equation for this titration.
