A student performs the following gravimetric analysis of iron ions in a water system:Fe2+ (aq) + 2CO32- (aq) = FeCO3 (s)If this student used excess carbonate and obtained the following data, what was the original concentration in moles/L) of Fe2+ in the water sample? Total Volume of Solution: 100.00 mLMass of FeCO3 collected: 23.758 grams.Is this how you would solve it change 100 ml to .1 liters. 115.853x = 23.758 x .1 = .02 liters.
Calculate the pH during the titration of 100.0 mL of 0.200 M HCl with 0.400 M NaOH. First what is the initial pH (before any NaOH is added)? - What is the pH after 38.4 mL of NaOH are added?
A 0.16 mol dm-3 solution (3.50 cm3) of s-butyllithium in toluene was added to a solution of styrene (8.40 g) in toluene (200 cm3). After complete conversion of the styrene, isoprene (28.00 g) was added. When the isoprene had completely polymerized, t..
