sucrose and reducing sugars dissolve 0.5 g in 10 ml of water by the addition of 2 ml of hydrochloric acid, and boil the solution for about 2 minutes. Cool, add 15 ml of sodium carbonate ts, allow to stand for 5 minutes, and filter. Add 5 ml of the clear filtrate to about 2 ml of alkaline cupric tartrate ts, and boil for 1 minute: no red precipitate is formed immediately.
assay dissolve about 600 mg of calcium saccharate, accurately weighed, in 150 ml of water with the aid of a sufficient volume of hydrochloric acid. While stirring, preferably with a magnetic stirrer, add about 30 ml of 0.05 m edetate disodium vs from a 50-ml burette. Add 15 ml of 1 n sodium hydroxide and 300 mg of hydroxy naphthol blue, and continue the titration to a blue endpoint. Each ml of 0.05 m edetate disodium is equivalent to 16.01 mg of c6h8cao84h2o.
