5. If the 0.2124 of potassium iodate are dissolved to make 250ml of solution what is the molarity? 6. If you remove a 25ml aliquot of potassium iodate from the 250ml of solution, a. How many moles potassium iodate is this? b. How many moles of iodate ions is this? 7. Calculate the moles represented by 0.5 g of potassium iodide. How many moles of iodide will this create? 8. Calculate the moles represented by 2.00 mL of 1.00MH2SO4. How many moles of hydrogen ions will this create? 9. Use equation (1) below and your answers to 6,7 , and 8 to calculate the limiting reagent. Use your answer from #9 to calculate the moles of I2 that will be produced by the limiting reagent. 10. Using your moles of I2, use equation (2) below to find the moles of Na2 S2O3 necessary for a complete reaction. 11. If you used 25.30 mL of Na2 S2O3 to do the titration, use the moles of Na2 S2O3 from 10 and the volume to find the molarity. 12. Read through the lab and have a carefully organized lab set up where each piece of data you will enter has a labeled spot. For example, for each titration that you will perform. you will need a spot to record the initial
