A sample of iron weighing 1.227 g is dissolved in 1.00 M HCl. The minimum volume of HCl that is required to dissolve the Fe is 4.39×101 mL. (Fe dissolves in HCl to form Fe2+)

a) When an excess of Na2S solution is added to the above solution, FeS precipitates. What mass of FeS should be obtained?

b) If 1.86 g of FeS were obtained, what was the percent yield of the product, FeS?

To determine the amount of iron in a dietary supplement, a random sample of 15 tablets weighing a total of 20.622 g was ground into a fine powder. A 3.0202-g sample of the fine powder was dissolved in 150 mL of water along with 1.2 g of urea, NH2CONH2. The solution was heated, which made the solution slowly turn basic as hydroxide was formed by decomposition of urea. As the solution turned basic, solid Fe(OH)3 formed. NH2CONH2 + H2O →...

Samples containing magnisium sulfate weighing 0.3546, 0.3412, and 0.3553 were dissovled in dilute HCl. Barium chloride solution is added in excess to precipitate barium sulfate. Approximatley how many mililiters of 5% BaCl2 solution would be required to precipitate all the sulfate if we assume that the samples are pure magnesium sulfate? Assume that the density of the barium chloride solution is 1.00 g/mL.

A 0.198-g sample of parsley is pyrolyzed and diluted with 8.00 mL of 1.0 M HCl. A 0.1-g crystal of NaSCN is added to the solution. The concentration of the prepared solution is determined to be 0.0965 mM in [FeSCN]2+. Based on this result, what is the mass of Fe in a 100-g sample of parsley? the answer is 21.8 mg Fe but i dont know why

A 1.379-g sample of commercial KOH contaminated K2CO3 by was dissolved in water, and the resulting solution was diluted to 500.0 mL. A 50.00-mL aliquot of this solution was treated with 40.00 mL of 0.05304 M HCl and boiled to remove CO2. The excess acid consumed 4.55 mL of 0.04925 M (phenolphthalein indicator). An excess of neutral BaCl2 was added to another 50.00-mL aliquot to precipitate the carbonate as BaCO3. The solution was then titrated with 28.56 mL of the...

A 0.4016 g sample of impure sodium carbonate (soda ash) is dissolved in 50 mL of distilled water. Phenolphthalein was added and 11.40 mL of 0.09942 M HCL was required to reach the first end point. Excess volume of HCL was added according to the lab procedure (if x is the amount of acid needed to complete the first titration, you will add a total of 2x + 10mL of acid to ensure excess). After boiling, the excess acid was...
