In a test tube you add 2 mL of saturated chlorine water followed by about 1 mL of an organic solvent such as heptane (or cyclohexane). The test tube is shaken and you notice that the heptane layer has a yellow color. To this mixture you then add 1 mL of 0.1 M Na l. After shaking you notice a color change from yellow to purple in the heptane layer. What can you conclude about Cl2 and I minus from this experiment? Cl, is reduced while I minus is oxidized | minus is an oxidizing agent and Cl2 is a reducing agent Cl2 is oxidized while I minus is reduced Nothing, more experiments are required to make a conclusion.

Suppose you want to measure the amount of glucose in a can of soda. You can use the data generated in this experiment to help you, but what other data would you need to collect in order to measure the concentration of glucose in the soda? In other words, what additional experimental step(s) would you perform? B I U Ꭶ X X, 14▾ A In order to measure the amount of glucose in a can of soda, one would need to prepare a series of standard solutions w/ an unknown concentrations of glucose using the 0.3M of glucose sol'n and DI water. Therefore, the glucose oxidase assay would be performed on each standard sol'n and the result values would also be measured by a spectrophotometer. A standard curve may then be plotted by absorbances and the unknown concentration of glucose. It may also be necessary to adjust the pH of the soda can sample to preform additional steps.

Imagine you are preparing a solution of NaCl and a solution of CaCl2. After you prepare them you go out to lunch with your colleagues. When you come back you cannot remember which solution is in which container because you forgot to label the containers before going to lunch. What experiments can you perform to identify each solution?
I'm stuck on a homework question. Any help would be great
Calculate the volume (mL) of 1.0 M metal nitrate solution required to prepare 5.0 g of the COBALT pigment. Again, using the balanced chemical equation you should be able to relate the moles of pigment to the moles of metal nitrate and from that calculate the volume of 1.0 M metal nitrate solution required. Please report your value as XX.X mL (one decimal point and no units).
Part 3: What mass of tin was used to make the tin solution? In a similar experiment, a sample of tin metal was dissolved in nitric acid to produce 28.00 mL of solution containing Sn²+.
