Question

Which for the following is considered a weak base? A. Lithium hydroxide B. Sodium hydroxide C. Calcium hydroxide D. Aluminum hydroxide Thanks!

Answer 1

Well `D.` is probably the best answer....

Explanation:

We gots `Al(OH)_3`...even tho this is still a basic species. `"Alumina"`, `Al_2O_3`, is an amphoteric oxide...that could act as an acid. The hydroxides of lithium, calcium, or sodium, all give rise to basic solutions....
