Factors That Affect Solubility:

Amphoterism

• Amphoteric oxides will dissolve in either a strong acid or a strong base.

• Examples: hydroxides and oxides of Al3+, Cr3+, Zn2+, and Sn2+.

• The hydroxides generally form complex ions with four hydroxide ligands attached to the metal:

• However, hydrated metal ions act as weak acids.
