Problem- Extension to Lab 3-1 Identify the visible absorption spectrum of an aqueous solution of sugar. 3 charts are shown a.Absorbance at 2.0, b.absorbance at 0, and c.absorbance curve at 1 trending down to 0 all on the 400 to 700 scale. So if glucose is transparent to visible light at 400-700 wv. What would absorbance would be?
