At 25^∘ C, 50.00 mL. of a 0.1000 m solution of maleic acid, a diprotic acid whose ionization constants are K21=1.42 ×10^-2 and Ks 2=8.57 ×10^-7, is titrated with a 0.1000 m NaOH solution. Calculate the pH at the following volumes of added base: 0,5.00,25.00,50.00,75.00,99.90,100.00, and 105.00 mL. | Numerade

When maleic acid is heated to 200^∘ C, it loses water and becomes maleic anhydride. Fumaric acid, a diastercomer of malcic acid, requires a much higher temperature before it dehydrates; when it does, it also yields maleic anhydride. Provide an explanation for these observations.

Maleic acid is prepared by the catalytic oxidation of benzene. It is a dicarboxylic acid; that is, it has two carboxylic acid groups. (a) Combustion of 0.125 g of the acid gives 0.190 g of CO2 and 0.0388 g of H2 O . Calculate the empirical formula of the acid. (b) A 0.261-g sample of the acid requires 34.60 mL of 0.130 M NaOH for complete titration (so that the H ions from both carboxylic acid groups are used). What is the molecular formula of the acid? (c) Draw a Lewis structure for the acid. (
