Hydrazine Hydrate analysis principles? Sample was added sulfuric acid to form a stable hydrazine sulfate, in the presence of sodium bicarbonate titrated with iodine solution to color indicate the end of excess iodine solution analysis points? Said vials must be added 5 ~ 10ml of water, said sample is about 0.04g (drop), said after the completion of the need to make up 50ml sample of distilled water. ? Added 1ml (1 + 5) after sulfuric acid can not add sodium bicarbonate immediately, we must allow the sample to form a stable hydrazine sulfate, add 1g of sodium bicarbonate, shake. ? Titration with iodine standard solution, the solution appeared yellow and keep 1min not disappear shall end two protective measures respiratory protection: its possible exposure to vapor or smoke, should wear protective masks.
