Practical physiological chemistry : a book designed for use in courses in practical physiological chemistry in schools of medicine and of science . Direct-vision Spectroscope. 2. Haemoglobin (so-called Reduced Haemoglobin).—Toblood which has been diluted sufficiently to show well definedoxyhemoglobin absorption-bands add a small amount of Fig. Angular-vision Spectroscope Arranged for Absorption Analysis. Stokes The blood immediately changes in colorfrom a bright red to a violet-red. The oxyhemoglobin hasbeen reduced through the action of Stokes reagent and 1 Stokes reagent is a solution containing 2 per cent ferrous sulphate and3 per cent tartaric acid. When needed for use a small amount should beplaced in a test-tube and ammonium hydroxide added until the precipitatewhich forms on the first addition of the hydroxide has entirely produces ammonium ferrotartrate which is a reducing agent. BLOOD. I7I haemoglobin (so called reduced haemoglobin) has been has been brought about by the removal of some of theloosely combined oxygen from the oxyhemoglobin. Examinethis haemoglobin spectroscopically. Note that in place of thetwo absorption hands of oxyhemoglobin we now have a singlebroad hand lying almost entirel) between 1) and E. This is Fig. 63.
