化学的性質 · 1 件

化学的特性Iron(II) sulfate hydrate, also known as ferrous sulfate hydrate, is Off-white to beige powder. Astringent odor. Mainly composed of FeSO4.H2O and contains a small amount of FeSO4.4H2O. harder to oxidize, and easier to store than crystalline ferrous sulfate. The aqueous solution is acidic and turbid, gradually producing a yellow-brown precipitate. It absorbs water into heptahydrate in humid air. Heating to 120 ℃ does not lose water. Boiling with water can be converted into alkali sulfate. Slowly soluble in cold water (26.6g/100ml, 20℃), rapidly dissolved when heated. Insoluble in ethanol. Almost insoluble in 50% sulfuric acid.

応用分野

解説硫酸鉄(II)七水和物FeSO4・7H2Oの古い俗称．ローハという読み方もある．

使用Iron(II) sulfate hydrate has been used to prepare ferrous ion solution to study the influence of iron ions on the thermal decomposition behaviour of hydroxylamine/water solutions.

調製方法 · 1 件

製造方法It is obtained by drying crystallized ferrous sulfate into powder at 40℃. Heating to 45 ~ 50 ℃ when dissolved in the water of crystallization and liquefaction, while stirring and slowly evaporating the water of crystallization. The limit of dry weight loss is 35%~36%, generating a small particle state fine powder, made of powder, sealed and stored.
