Ferrous sulfate effect on plants. The ablation ferrous sulfate water pH adjusted to about PH4. Way is to add high-quality rice vinegar to the water or dilute sulfuric acid, measuring pH in the water with litmus paper, start to not add a little, test once, ferrous sulfate, until the water PH value adjusted 4 so far. Then add ferrous sulfate solution and then with litmus paper test once, if PH value is still about 4, you can use this watered ferrous sulfate solution due to iron deficiency and yellow flowers. General condition only flowers and plants iron chlorosis, PH value must be higher pot, watered with ferrous sulfate solution will make this low PH value PH value of the basin of the lower number, and then reach for the addition of iron deficiency flowers target element. Laboratory Process 1, can react with iron and sulfuric acid prepared directly. Fe + H2SO4 (diluted) = H2 ↑ + FeSO42, can be obtained by reacting with the iron sulfate solution, Henan how much ferrous sulfate, the reaction equation is: CuSO4 + Fe = FeSO4 + Cu (This type of reaction is a substitution reaction) Toxicology Information health hazard: respiratory irritant, the price of ferrous sulfate, inhalation causes coughing and shortness of breath. The eyes, skin and mucous membrane irritant. Coverage cause weakness, abdominal pain, nausea, bloody diarrhea, lung and liver damage, shock, coma, severe cases can be fatal. Environmental hazards: hazard to the environment, the use of ferrous sulfate, can cause pollution of water bodies. Explosion hazard: This product is flammable, irritating. Toxicology data (LD50) :( mouse, oral) 1520mG / kG. The use of ferrous sulfate, ferrous sulfate _ _ Zhengzhou Longda Chemical (Views) provided by the Zhengzhou Longda Chemical Products Limited.
