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.
Phenols are aromatic rings with an alcohol functional group attached directly to the ring. These compounds have unique acidity and solubility for alcohol groups. Phenolic functional groups are weak acids. Predict the solubility of the conjugate base of phenol in water.
Please answer question 5A, 5B, and 5C.
