- Aspirin is prepared by the reaction of salicylic- acid with acetic anhydride as shown in the following equation. The stoichiometry of the reaction is given in the equation. Acetic acid is a by-product of the reaction and must be separated and removed so that aspirin can then be sold as a pure product. How many grams of aspirin can be prepared from 120 grams of salicylic acid? Assume that there is an excess of acetic anhydride.

Dehydration of two molecules of methanol under acidic condition (H2SO4) at high temperature will produce * Acetone Ethanal Acetic acid Methoxymethanearrow_forwardCream of tartar is a white powder sometimes used in baking. (It's what separates a tangy, chewy snickerdoodle from an ordinary cinnamon-coated sugar cookie. The acid in the cream of tartar gives snickerdoodles their distinctive tangy flavor, and the chew happens because cream of tartar prevents sugar in the cookie dough from crystalizing into crunchiness. Allrecipies.com) Cream of tartar (KHC4H4O6) is the conjugate base salt of tartaric acid (shown to the right). The Ka for another similar acid is 8.7×10-3.

O Phenols are generally only slightly soluble in water. O The hydroxyl group of an alcohol is nonpolar. The solubilities of normal primary alcohols in water decrease with increasing molecular weight. Boiling points of normal primary alcohols increase with increasing molecular weight.arrow_forward
