Sodium hydroxide (NaOH), aswell accepted as
lye and abrasive soda,is an asleep compound. It is a white solid and awful
abrasive brownish abject and acrid acrid of sodium which is accessible in
pellets, flakes, granules, and as able solutions at a bulk of altered concentrations.Sodium
hydroxide forms an about 50% (by weight) saturated band-aid with water.
Sodium hydroxide is acrid in water,
ethanol, and methanol. This acrid is aqueous and readily absorbs damp and
carbon dioxide in air.
Pure sodium hydroxide is a blanched solid,
awash in pellets, flakes, and diminutive form, as able-bodied as in solution.
It is awful acrid in water, with a lower solubility in booze and methanol, but
is baffling in ether and added non-polar solvents.
Similar to the hydration of sulfuric acid,
dissolution of solid sodium hydroxide in baptize is a awful exothermic
acknowledgment in which a ample bulk of calefaction is liberated, assuming a
blackmail to assurance through the achievability of splashing. The consistent
band-aid is usually colourless and odorless. As with added acrid solutions, it
feels glace if it comes in acquaintance with skin.
