- Complete the following reaction COOH NO,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.CARBON 5 1 H 1.008 Circle and name ALL the functional groups in this molecule HO O 6 с 12.01 CH 3 | но H 1 C-C-C-C-N | || | OH Indicate which carbon/s in the molecule would be asymmetric What is the molecular formula of this molecule: Draw the group that serves as an ACID and show it in ionized form There are two groups that can become IONIZED (lose or gain H*).

- Phenol, C6H5OH, is an acidic organic compound for which K₂ = 1.3 x 10-10. The structure of phenol is a benzene ring with an -OH replacing a hydrogen atom on one of its six carbon atoms. Because phenol has this -OH group, you might think that the -OH would ionize and make phenol a base. Actually, the O-H bond is very weak and phenol acts as an acid by ionizing the H* ion. What is the pH of a 0.47 M solution of phenol in water? pH=ễ3. For the following acid - base reaction, (a) predict the products; (b) identify the Bronsted acid, Bronsted base, conjugate acid, and conjugate base; (c) use curved arrows to show the flow of electron pairs in the reaction.
