- Maleic acid (H2C4H2O4, represented by H2M) is the precursor of malic acid widely used in industry. food as an acidulant and in the pharmaceutical industry it is used in the treatment of wounds. This acid can be determined by neutralization titration. Answer the items below about this determination. a) Considering a 15.0 mL sample of maleic acid-based product used in industry, determine the maleic acid concentration, in mol/L, in the sample knowing that 21.7 mL of a solution of 0.1120 mol/L NaOH for complete neutralization of this acid. How many grams of maleic acid were in the sample analyzed and what is its percentage (%, m/v) in the sample? [Answer; m=0.1405 mol/L; percentage = 0.9365%] NaOH(aq) + H2M(aq) ----> Na2M (aq) + H2O(l) b) And Suggest an appropriate indicator for the titration of this acid by looking at the titration curve profile below (image)Each row of the table below describes an aqueous solution at about 25 °C.
