0.1200 g of potassium dichromate primary standard is dissolved, quantitatively transferred into a 250-mL volumetric flask and diluted to volume. 0.3000 g an unknown iron ore sample was dissolved in hydrochloric acid, treated with stanous chloride and mercury(II) chloride, quantitatively transferred to a 100-mL volumetric flask and diluted to volume. 25.00 mL of the unknown iron(II) solution was pipetted into 500-mL Erlenmyer flask and titrated with the potassium dichromate solution. 28.00 mL of potassium dichromate is required to reach the...

A compound with molecular mass = 292.16 g/mol was dissolved in a 5.000 mL volumetric flask....

A compound with molecular mass = 292.16 g/mol was dissolved in a 5.000 mL volumetric flask. A 1.000 mL aliquot was withdrawn, placed in a 10.000 mL flask and diluted to volume. The apparent absorbance of the diluted solution at 340 nm was 0.827 in a 1.000 cm cuvette. To check for a possible stray light effect, this sample was diluted by exactly a factor of 2; the apparent absorbance was now 0.421. A reagent blank showed negligible absorbance. The...

1.25-g of BaCl2 is placed in a 4.000 L volumetric flask. Then the volumetric flask is filled with D.I. water to the 4.000 L mark. All the BaCl2 goes into the solution. Assume the density of the solution is 1.00 g/mL. What is the mass/mass (m/m) % and the mass/volume (m/v) of the solution?

10 mL of bleach with an unknown concentration is added to a 100mL volumetric flask. The...

10 mL of bleach with an unknown concentration is added to a 100mL volumetric flask. The solution is then finished with deionized water. 10 mL of this diluted bleach solution is then added to an erlenmeyer flask along with 1 scoop of KI, and 5 L of 2M HCl. This solution is then titrated with Na2S2O3 until it is a pale yellow color, then a starch indicator is added and titration is completed until the solution is clear. If 43...
