C.I. Solubilized Sulfur Brown 10 - Introduction
Sulphur Brown 10 -Solubilised is a commonly used inorganic ammonium oxalate reagent, chemical formula (CHO2)2C(NH4)2, also known as oxalic acid two ammonia ammonium. The following is a description of its nature, use, preparation and safety information:
Nature:
Sulphur Brown 10 -Solubilised is a water-soluble white crystalline solid with a pungent taste. It has good solubility and stability, can be quickly dissolved in water, and can form a neutral solution. Sulphur Brown 10 -Solubilised has a melting point of 70°C and a density of 1.5g/cm³.
Use:
Sulphur Brown 10 -Solubilised is widely used in chemical laboratories and industrial production. Commonly used in oxalic acid analysis, heavy metal ion precipitation, water treatment and other fields. It can be used to determine the concentration of oxalic acid by reacting with oxalate ions to produce a brown precipitate. In addition, Sulphur Brown 10 -Solubilised can also be used as reagents, catalysts and dye intermediates.
Method:
Sulphur Brown 10 -Solubilised can be obtained by the reaction of ammonium oxalate with hydrogen sulfide. The reaction is as follows:
(CHO2)2C(NH4)2 H2S → (CHO2)2CS 2 NH4HS
Safety Information:
Sulphur Brown 10 -Solubilised is harmless at certain concentrations. However, during operation, it is still necessary to pay attention to safety precautions, such as wearing protective glasses and gloves to ensure good ventilation. Avoid contact with oxidants during storage and handling to prevent fire or explosion. If ingestion or contact with skin or eyes, rinse immediately with water and seek medical help.
