Question
In this experiment, we will be making waste aluminum into Select one: Q: 1 Aluminum foil to use in other lab procedures Aluminum spatulas to use in future experiments O Aluminum nitrate, which will be used in the "Missing Labels' experiment for next year O Alum, a potential ingredient in deodorant Assuming you start with 1.25 g of pure aluminum, calculate the following: 1) The amount of potassium hydroxide, KOH, in grams, needed to react with all of the 1.25 g of Al. The reaction is: 2 Al (s) + 2 КОН (аq) + 6 Н,0 (1) — 2 K (аq) — 2 AI(ОН)4 (аq) + З Н2 (g) Q:Z 2) The amount of KOH needed, in grams, in reaction 1 if you want to have 10% excess KOH. g 3) The amount of water, in milliliters, that will react with the Al and KOH in reaction 1. mL 4) The amount, in milliliters, of 9 M sulfuric acid needed for reaction 2. 2 Al(OH), (aq) + H2SO4 (aq) –→ 2 Al(OH)3 (s) + so,2- (aq) + 2 H2O (1) 5) The amount, in milliliters, of 9 M sulfuric acid needed for reaction 3. 2 Al(OH)3 (s) + 3 H2SO4 (aq) → 2 Al* (aq) + 3 So,2- (aq) + 6 H2O (1) mL What is one potential source of major contamination in this experiment? Select one: Q:3 O Paint and plastic coating on the can O Boron, which is also a group 3A element Dust from the air O O O C
