解説硫酸亜鉛，りゅうさんあえん，亜鉛の硫酸塩で、通常は七水和物がよく知られ、皓礬(こうは)とよばれる。天然には無水和物および七水和物が産出する。工業的には硫化亜鉛を適当に煆焼(かしょう)して無水和物が得られる。金属亜鉛または酸化亜鉛、炭酸亜鉛を希硫酸に溶解し、濃縮冷却して39℃以下で結晶化すると七水和物が、39～70℃で結晶させると六水和物ZnSO4・6H2Oが、さらに70℃以上では一水和物ZnSO4・H2Oが得られる。七水和物は無色・無臭。収斂(しゅうれん)性のある結晶。空気中では風解する。急に熱すると約50℃で結晶水に溶けるが、穏やかに熱すると39℃で六水和物となり、70℃では一水和物となるが、さらに240～280℃では無水和物となる。水に易溶。水溶液は加水分解して弱酸性。エタノール（エチルアルコール）に難溶。

使用Zinc sulfate heptahydrate is widely used as a coagulant in the production of rayon. It finds an application in the manufacturing of calico printing, wood preservation and lithopone. It is the source of zinc which is supplied in animal feeds, fertilizers and agricultural sprays. It is utilized as electrolytes for zinc plating and surface treating agents. It is also used as a mordant in dyeing, preservative for skin and leather and in medicine as an astringent and emetic.

一般的な説明Zinc sulfate heptahydrate has various industrial applications. It is widely employed as an electrolyte for zinc electroplating and for the storage of solar energy in various solar appliances. Its crystals exhibit diamagnetism.

調製方法 · 1 件

純化方法Crystallise it from aqueous EtOH or dilute H2SO4 below 39o when it forms the heptahydrate, and between 39o and 70o it forms the hexahydrate, and above 70o the monohydrate is stable. The anhydrous salt is obtained from the hydrates by heating at 280o or lower temperatures in a current of dry air. It decomposes to ZnO and SO2 at 767o. The solubility of the heptahydrate in H2O is 5.88% at 0o, 61.92% at 30o, 66.61% at 35o and 70.05% at 39o.
