Sodium hydroxide (Caustic soda) is a Solid, odorless, crystalline, white and translucent solid foam, in the form of flakes or granules, It is non-volatile and has high corrosive properties, which easily absorb air moisture And it’s one of the most important industrial chemicals.
Caustic Soda flakes (NaOH)
Dissolving caustic soda in water is an exothermic process, It’s dissolves in water, releasing a lot of heat. In contact with the skin, it has a corrosive effect And to avoid the effects of burning, it should be taken into consideration when using it.
