Enter your answer in the provided box. The SO2 present in air is mainly responsible for the phenomenon of acid rain. The concentration of SO2 can be determined by titrating against a standard permanganate solution as follows: 58O2 + 2MnO4 + 2H20 - 55042- + 2Mn2+ + 4H Calculate the number of grams of So, in a sample of air if 3.50 mL of 0.00700 M KMnO4 solution are required for the titration.

Scientists determine the quantity of atmospheric sulfur dioxide (SO2), a large contributor to acid rain, by an indirect titration. First, a scientist collects a sample of air and reacts it with hydrogen peroxide (H,O,) to form a solution of sulfuric acid ( H, SO2). Then, the amount of H, SO, produced is determined by titration with a sodium hydroxide solution (NaOH) of known concentration. H,02(aq) + SO2(g) → H, 50,(aq) H, SO (aq) + 2NaOH(aq) + 2 H2O(l) + Na,...

A titration is a procedure for determining the concentration of a solution by allowing it to react with another solution of known concentration (called a standard solution). Acid-base reactions and oxidation-reduction reactions are used in titrations. For example, to find the concentration of an HCI solution (an acid), a standard solution of NaOH (a base) is added to a measured volume of HCl from a calibrated tube called a buret. An indicator is also present and it will change color...
