Page 173 - To tubes 2, 3, 4, and 5 add 0.5 cc. of distilled water. (c) From tube 2 remove 0.5 cc. of its mixed contents and add to tube 3. Mix 'thoroughly and add 0.5 cc. from tube 3 to tube 4. Repeat for tube 5. We now have dilutions of gastric
Page 369 - The titration is performed in the presence of nitrous acid and starch, so that the first drop of iodide in excess of the silver present is changed to free iodine and gives the blue starch-iodine color. The optimum acidity for the end-point is fixed by the addition of trisodium citrate in amount equivalent
