(sodium sulfide) is the salt (product) of the reaction of , a weak acid, and, a strong base, The resulting reaction is a neutralization reaction.
- Due to the presence of additional ions formed by the hydrolysis of ions, the aqueous solution of such a salt is predominantly alkaline (alkaline).
- Thus, is primarily a basic salt, and so on.
Hence, is neither an acid nor a base, it is a salt.
