Sodium Hydroxide/Caustic Soda Flakes

When the Flake sodium hydroxide is opened, it attracts the water vapor of the air (moisture absorption). Sodium hydroxide dissolves like ethanol or glycerin. Spanish pearl alkali is a strong corrosive alkaline substance, which can make phenolphthalein test paper red and litmus test paper blue after dissolving in water. There are two kinds of caustic soda: solid and liquid: pure solid caustic soda is white, massive, flaky, rod-shaped, granular, brittle; pure liquid caustic soda is colorless and transparent liquid. Sodium hydroxide is also easily soluble in ethanol and glycerin, but not in ether, acetone and liquid ammonia. Sodium hydroxide, also known as alkali or caustic soda, has a general formula of NaOH and is a highly corrosive metal substrate. It is a white solid, which can be in the form of pellets, tablets or granules, although sometimes it is in the form of a 50% saturated solution.
Sodium hydroxide in flake form is sometimes referred to as sodium hydroxide solution. It should be noted that sodium hydroxide tablet is a dangerous chemical. When diluting with water, it is necessary to slowly add water into sodium hydroxide tablet and keep stirring. At the same time, a large amount of heat will be released during the dilution process, and the temperature needs to be controlled. If the addition sequence is reversed or the mixing is not timely, the danger will occur
