in the hydrate experiment blue CuSO4 was dehydrated to a white solid. what happened when water was added again and why?
in part one f the iron absorbance lab, was the first calculation needed
should points used for the slope of a calibration curve be close together or far apart?
in the Spectrometer determination lab what are the Y and X values on the graph
does absorbancy have units?
in part 2 of the spectrometric determination of Iron experiment how was the total iron in the well water sample calculated?
in the sepectrophotometric determination of iron experiment, before the absorbancey can be measured Iron(III) has to be reduced to Iron (II) using NH2OH. Write the balanced reaction equation.
Fe2+ is then added to a weak base and is then ready for absorbance measurements. Write the balanced equation of this reaction.
