9. An aqueous solution of sulfuric acid is prepared by mixing a secondary standard of sulfuric acid with deionized water. The aforementioned acid is to be used as a titrant hence its concentration must be accurately determined. To do this, Engr. Polinar, standardized the titrant by titrating two liters of ammonia at 0.90 atm and 30 deg C. From the experiment, 134 mL of the titrant was necessary to neutralize the ammonia. Determine the concentration of the acid in terms of normality? 10. Engr. Forcadela is optimizing a plastic formulation by manipulating the phosgene concentration injected as a gas during the reaction. To obtain credible results, he considered the propensity of phosgene to dissociate into carbon monoxide and chlorine gas at 395 deg C. Performing an experiment at the aforementioned temperature, an equilibrium is reached amongst the species where the total pressure is at 3 atm. If the equilibrium constant expression in terms of concentration for the reaction at 395 deg C…

For the CO2 impact experiment station: 1) Obtain two plastic cups, red cabbage indicator, a straw, and plastic wrap. 2) Fill each cup approximately one-quarter to one-third full of tap water and add ~10 mL of the red cabbage indicator. 3) Place the two cups side by side on a sheet of white paper. 4) Place the straw into one of the beakers and cover that beaker with the plastic wrap. 5) Carefully blow bubbles into the test cup for 3 min. and observe both cups. 6) Compare the color to the control cup and record any differences. This the Question: Did the beaker with the solution into which CO2 was bubbled change pH/color? By how much? Is this what, you would predict, based on your knowledge of the chemistry of CO2?

The amount of I5 (aq) in a solution can be determined by titration with a solution containing a known concentration of S₂O3(aq) (thiosulfate ion). The determination is based on the net ionic equation 2S₂O3(aq) + 13(aq) →SO (aq) +31-(aq) Given that it requires 41.0 mL of 0.450 M Na₂S₂O3(aq) to titrate a 20.0 mL sample of I3 (aq), calculate the molarity of 15 (aq) in the solution.
