產品簡介：
氯氣和氫氣反應合成氯化氫的水溶液，由于在工業生產中夾有鐵等微量雜質，故呈現為淡黃色。它具有刺激性臭味，是一種可揮發性強酸，有毒，有腐蝕性，容易和許多金屬反應，可與堿金屬和堿土金屬反應，也可與許多金屬氧化物以及多種金屬鹽起反應。在冶金、紡織、皮革、醫藥等行業都有廣泛的應用。

Refined Hydrochloric acid
Introduction of product:
HCL solution formed by Cl 2 and H 2 is light yellow due to a small quantity of impurities such as Fe in industrial production. It is of strong acidity with irritant odour, volatile, poisonous and erosive, prone to react with many metals, including alkali metals and alkali earth metals, many metallic oxide and metallic salts. It is very popular with many fields, such as metallurgy, textile, leather and pharmacy industry.
