[cu(nh3)4]2+ solutions exhibit a deep blue-violet color. how can you use spectrophotometry to confirm that this reaction has occured and that the product formed is in fact tetraaminecopper(ii) sulfate? would you expect the wavelength of maximum absorbance for cu(nh3)4 2+ to be greater than or less than the max absorbance for cu(h2o)6 2+? explain.

28. which is not a reason that water is used to store spent fuel rods from nuclear power plants? water increases the speed of the chain reaction in the fuel rods. water protects nuclear power plant workers from the high temperature and radiation of the fuel rods. water acts as a radiation shield to reduce the radiation levels. water cools the spent rods. salts action
