A 3.963-g sample of coal was burned in a tube furnace and the liberated SO2 was collected in dilute H2O2, which converts the SO2 to sulfuric acid:
SO2(g) + H2O2(aq) ---> H2SO4(aq)
A 25.00-mL portion of 0.01302 M NaOH was added to the resulting solution of H2SO4, and the excess base was back-titrated with 7.97 mL of 0.01137 M HCl. Report the sulfur in the coal sample as ppm S.
Calculate the molarity of a solution made by dissolving 0.150 mol Na2SO4 in enough water to form exactly 760 mL of solution.
Describe the apparent relationship between H3O and OH concentrations when an endpoint is reach in acid-base titration.
Calculate the transformation rate for the austenite-to-pearlite transformation at 650 °C and at 600 °C. Show the relationship(s) you used to arrive at your answers.
