Chemical Information
FooDB NameSodium hydroxide (NaOH)
DescriptionSodium hydroxide (NaOH), also known as caustic soda or aetznatron, belongs to the class of inorganic compounds known as alkali metal hydroxides. These are inorganic compounds in which the largest oxoanion is hydroxide, and in which the heaviest atom not in an oxoanion is an alkali metal. Sodium hydroxide (NaOH) is an extremely weak basic (essentially neutral) compound (based on its pKa).
