Between 95-100% of all natural product might be oxidized by dichromate. After dichromate oxidizes a compound It can be transformed to some trivalent method of chromium, which is a uninteresting eco-friendly colour.
When all the surplus dichromate reacts, an equivalence issue is attained. This position signifies that the level of ferrous ammonium sulfate you additional is equal to the amount of excessive dichromate.
