ferrous sulfate heptahydrate la introductions

  • Ferrous sulfate

    Iron(2+) sulfate (anhydrous) is a compound of iron and sulfate in which the ratio of iron(2+) to sulfate ions is 1:1. Various hydrates occur naturally - most commonly the heptahydrate, which loses water to form the tetrahydrate at 57℃ and the monohydrate at 65℃. It has a role as a reducing agent.

    2017-6-20u2002·u2002forms a crystalline solid known as ferrous sulfate heptahydrate and precipitates from solution. As the temperature of the acid solution decreases from normal pickling temperature (45°C – 75°C) to 5°C, the iron continues to drop out at a near linear rate. This heat removal principle is the basis of acid recovery.
