6. Calculate Keam for the solution in flask F and the new Keam for the solutions in flasks D and E. Show your working. Record these in Table 2. Flask F D E Table 2 Vol. of AgNO3 (mL) 25 50 50 0.80 0.55 0.51 Concentration of Species (mol/L) Co(HzO)62+ 0.40 1.4 1.9 CI- 0.000058 0.0064 CoCl4²- 0.020 Red Colour Red (slight bit darker + grey) Darker greyish red Keam Constant 0.00018=1.8x1 0^4 0.0083 0.021 7. Compare the equilibrium constant for experiments involving the addition of HCI with those involving AgNO3. Are they the same? Should they be? Explain. 8. Consider Flask B. Sketch a graph showing (very roughly - i.e. higher or lower) the relative equilibrium concentrations of the 2 complex ions and the chloride ion against time before and after the addition of HCI. 9. Consider Flask F. Sketch a graph showing (very roughly - i.e. higher or lower) the relative equilibrium concentrations of the 2 complex ions and the chloride ion before and after the addition of AgNO3. 10. Consider Flask E. Sketch a graph showing (very roughly - i.e. higher or lower) the relative equilibrium concentrations of the 2 complex ions and the chloride ion from the very beginning of the experiment when the system is in equilibrium before the addition of HCI until equilibrium is regained after the addition of AgNO3.
