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
