Question type: Shopping & Pricing. I'm looking at buying a 2011 BMW 335 Manufacturer buyback that was originally from California. I've gotten over the stigma of buying a buyback,' since the car has been repaired by BMW, is still under warranty and the price is a lot closer to what I'm willing to spend. The reason it was bought back was for an extended crank issue, which has been completely resolved.
Do you think we can use the flame test to determine the identity of unknown in a mixture? Why or why not? I think that the flame test could be used to determine the identity of unknowns in a mixture, however it would not be very effective. This is because if there are to many different compounds, or elements, all of the colors of light mixed together would bring the flame closer to just emitting white light.
A standard curve is used to determine the concentration of a substance that is unknown. To start the standard curve test known concentrations of similar solutions, one way to do this is using a spectrophotometer to measure absorption when compared with concentration. standard curve is a tool used in research the concentration of substances quantitatively. It is used to find the concentrations of unknown substances. This is done by comparing the assay data of the unknown substance concentrations to that of the known.
