okay so i was given an experiment to do and now i have to write a lab write up. i need help with identifying the different chemistry topics in the lab(meaning like dilution, oxidation, aciids and bases, ex)
prepare 500 mL of a 3.5M H2SO4 soution. to this solution add enough potassium permanganate to make it 0.0006M with respect to potassium permanganate. (NOTE: there instructions do no direct you to make 200 mL of the acid solution and 200mL of the potassium permanganate solution and then to mix the two obtaining 400mL solution) stir the mixture well to insure that all the potasium permanganate is dissolver and that the composition of the solution is unifor throughout. put 10 mL of this solution in each of 5 test tubes. to the first test tube add one iron wire, to the second 2 iron wire, to the third 3 iron wire and so on. wait why did the solution in the test tube with 5 iron wires become decolorized more rapidly than the one with 4 wires and it in turn more rapidly with 3 wires and so on?
help please! it will be greatly appriciated! |
