4. You are titrating 100.0 ml of a solution containing unknown concentrations of Hg22* and Ba2* (as their soluble nitrate salts) with a solution of 0.134 M NazSO4. BaSO4 is over 1000 times more insoluble than Hg2SO4, so the added S0,² will react with the Hg22* in solution first, before reacting with the Ba* in solution. Below is the titration curve for the addition. The unit on the y-axis is not important. The unit on the x-axis is ml of 0.134 M NazSO4 added. Note the two equivalence points. What are the concentrations of the Hg2* and Ba2* in the 100.0 ml solution? 5 10 15 20 25 30

Scientists determine the quantity of atmospheric sulfur dioxide (SO, ), 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, 0, ) to form a solution of sulfuric acid ( H, SO, ). Then, the amount of H, SO, produced is determined by titration with a sodium hydroxide solution (NaOH) of known concentration. H,O,(aq) + SO,(g)– H, SO,(aq) H, SO, (aq) + 2 NaOH(aq) 2 H, O(1) + Na, SO4(aq) Suppose Lane collects a 608.0 g sample of air that is known to contain SO, and reacts it with excess H,O, . A volume of 17.8 mL of 0.010 M NaOH is required to neutralize the H, SO, produced. Calculate the mass percent of SO, in the air sample. mass percent: % SO2
