How to determine the main components of iron oxide red
1. Take a small amount of iron oxide red, the amount is 0.15 g and put it into a special reaction vessel, and then drop a small amount of acid onto the sample. Iron red products cannot be free of impurities. This method can check the ingredients. So add the acid again and heat it to boiling, then slowly add the stannous chloride test solution until it just becomes colorless. At this time, add one drop again, then pour water to 200ml, and cool. Black iron oxide has a strong effect, which can be reflected in the following composition test.
2. The iron oxide red component can be determined in the next step. The solution has been cooled to room temperature above. Now add 4 ml of mercury dioxide solution and mix it evenly. Add 3 ml of sulfuric acid and phosphoric acid respectively, and then Drop 6 drops of diphenylamine sodium phosphate solution, then use 0.01667mol/L potassium dichromate titrant to turn the liquid into purple-blue, and wait for half a minute. 1 ml of potassium dichromate is equal to 7.72 mg Iron oxide black.
