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.

- 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=ễarrow_forwardNote these acronyms: HOAC = Acetic Acid; NaOAc = Sodium Acetate; THE = tetrahydrofuran Ph = Phenyl = C6H5; DMSO = Dimethyl Sulfoxide, H3C-O-H = methanol, Zn = Zinc, D = heavy Hydrogen (1 proton and 1 neutron).
