WebA solution has a concentration of 2.56 x 10-2 M iron (II) thiocyanate with a molar absorptivity of 1.05 x 10-2 M-1 cm-1. What is the transmittance of the solution if it is in a 10.0 cm cell? Find the absorbance when the cell path length is … WebThe catalysts used are copper(II), cobalt(II) and iron(II) ions. Iron(III) ions are reduced to iron(II) ions in the presence of sodium thiosulfate. The reaction proceeds via a dark violet unstable complex but gives a colourless solution with time. Students can do this experiment in pairs or small groups. If each pair of students attempts this ...
WebPurpose The reaction of iron (II), Fe3 with thiocyanate, SCNT, to yield the colored product, iron (III) thiocyanate, FeSCN, will be studied and its equilibrium constant determined using a Vernier Spectrometer. This will require that first a graph that relates the concentration FeSCN to its absorbance be prepared.
