Production of Sodium Hydroxide Solution
Sodium hydroxide solution is produced industrially mainly by the electrolysis of sodium chloride. This yields sodium hydroxide solution, chlorine, and hydrogen.
Sodium Hydroxide: Properties and Uses
Sodium hydroxide is a strong base with the formula NaOH. In its pure form it is a white crystalline solid, but it dissolves easily in water to form a colorless solution.
Chemical Reactions in Industrial Processes
Chemical reactions are a fundamental aspect of many industrial processes. These reactions involve the transformation of one or more substances into new products.
