Complete the following table, making sure to include your units! Concentration of Concentration of acetic acid Water level on measuring cylinder before reaction 98 mL 91 mL 95 mL 0.5% 0.2% 0.1% ● sodium bicarbonate 0.5 M 0.5 M 0.5 M From the results above, which reactant do you consider to be the limiting reagent? Why? ● Water level on measuring cylinder after reaction 8 mL 49 mL 81 mL Consider the reaction where the concentration of acetic acid was 0.5% and the concentration of sodium bicarbonate was 0.5 M. Complete the table on page 5 to calculate the theoretical yield of CO2 with these concentrations. The following bullet points may help: You have already calculated the amount of sodium bicarbonate in 100 mL In a 100 mL solution of acetic acid at 0.1% there will be 0.1 mL of acetic acid. ● Volume of gas produced The density of acetic acid is 1.05 g/mL. You can use this value to calculate the mass of acetic acid used in the reaction.

c) Alum, KAl(SO4)2-12 H₂O is a soluble salt hydrate. Alum has several household and industrial uses. When placed in water alum dissociates into 3 ions and the water molecules become liquid water. Write the dissociation reaction of alum in water: Consider what you have learned about which ions under hydrolysis in water and which do not. Which ions hydrolyze in water? Write the hydrolysis reaction for each ion that hydrolyzes. Look over your Part II analysis and find the K, and/or Ks values for each of the ions that hydrolyze. Write the values next to their hydrolysis reactions above. Is alum is acidic, basic or neutral? How did you make your determination?
Add all four reaction steps together to get the overall reaction. Remember to cross out anything that occurs on both the reactant and product sides and to combine like terms. 1. 2 Al(s) + 2 KOH (aq) + 6 H2O (l) → 2 KAl(OH)4(aq) + 3 H2(g) 2. 2 KAl(OH)4(aq) + H2SO4 (aq) → 2 Al(OH)3(s) + 2 H2O (l) + K2SO4(aq) 3. 2 Al(OH)3(s) + 3 H2SO4 (aq) → Al2(SO4)3(aq) + 6 H2O (l) 4. Al2(SO4)3(aq) + K2SO4(aq) + 24 H2O (l) →2 (KAl(SO4)2∙12H2O) (s) For each reactant except water, calculate the number of moles you added (use the stoichiometry of the balanced equation to identify the limiting reactant.
