.. We want to determine the purity of alum sample bought in a local pharmacy in Miagao. A Chem 28 student determined the purity gravimetrically of a sample of alum, K2SO4·Al2(SO4)3•24H20. A 1.5879-g sample was dissolved and the aluminum precipitated as Al(OH)3. The precipitate was collected by filtration, washed, and ignited to give a product Al2O3 weighing 0.1572 g. Show your calculation to determine the purity of the alum sample.

In a terrible accident, a solution consisting of 2.37 kg of nitric acid, HNO3, was spilled on the lab floor. Very quickly, you decide to throw 2.00 kg of sodium carbonate, Na2CO3, on the spilled acid. You then run out of the building due to the significant quantities of carbon dioxide that would form due to the reaction. As you stand outside, you wonder, "Did I add enough sodium carbonate to neutralize the acid?". a) Did you add enough sodium carbonate to neutralize the acid? Yes Ο No b) In the event that you did not add enough sodium carbonate, how much extra would be needed to completely neutralize the acid? If you have added enough, please enter a value of 0 (zero). Needed 0 c) In the event that you did add enough sodium carbonate, how much extra did you add? If you didn't add any extra, please enter a value of 0 (zero). Excess 09 g g
Normal calcium levels in the blood should be between 9.0 and 10.5 mg/dL. Calcium levels in the blood can be determined by adding oxalate ion to precipitate calcium oxalate, CaC2O4, followed by dissolving the precipitate in aqueous acid and titrating the resulting oxalic acid (H2C2O4) with KMnO4. 5 H2C2O4 (aq) + 2 MnO4–(aq) + 6 H+(aq) yields 10 CO2 (g) + 2 Mn2+(aq) + 8 H2O(l) What is the concentration of Ca2+ (mg/dL) in a 10.0 mL sample of blood if 10.54 mL of 9.88 x 10–4 M KMnO4 solution is needed for the titration.
A chemist performs a gravimetric analysis. The chemist combines 1.00 L of 2.00 M AGNO, (ag) with 1.00 L of 4.00M NaCl (ag) in an Erlenmeyer flask. Both the AgNO3 (aq) solution and the NaCl(aq) solution are colorless. After the mixture has been stirred, a cloudy white substance is observed at the bottom of the flask. What is the expected mass of AgCl (s), in grams, assuming that the yield is 100%? In the box, enter the mass to the nearest gram.

The concentration of SO32- in a solution is determined by titrating it with a 0.1464 M dichromate solution. The balanced net ionic equation for the reaction is: Cr₂O72-(aq) + 3SO32(aq) + 8H30*(aq) → 2Cr³+ (aq) + 3504²(aq) + 12H₂O(l) In one experiment, 23.91 mL of the 0.1464 M dichromate solution is required to react completely with 30.00 mL of the SO32- solution. Calculate the concentration of the SO3²- solution. M

A chemistry student needs to standardize a fresh solution of sodium hydroxide. She carefully weighs out 316.mg of oxalic acid H2C2O4 , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in 250.mL of distilled water. The student then titrates the oxalic acid solution with her sodium hydroxide solution. When the titration reaches the equivalence point, the student finds she has used 93.2mL of sodium hydroxide solution. Calculate the molarity of the student's sodium hydroxide solution. Be sure your answer has the correct number of significant digits.
A sample of iron ore is dissolved in acid, and the iron is converted to Fe2*. The sample is then titrated with 47.20 mL of 0.02240 M MnO4 solution.
