1、 Overview
Molecular formula: NaOH, molecular weight four0.00.
nature:The pure product is a flake or bead white solid. It is highly hygroscopic, easily soluble in water and strongly exothermic. 3two% aqueous solution is colorless to yellowish, greasy liquid, strongly alkaline. It is highly corrosive and has great corrosive force on skin, fabric, paper, etc. Easily absorb carbon dioxide from the air and gradually turn into sodium carbonate.
IIpurpose：
It is one of the most important basic chemical raw materials. It is widely used in soap making, water treatment, papermaking, printing and dyeing, metal products, etc. it is also the raw material of basic chemical industry and other basic synthetic industries.
