What are the solubility rules for hydroxide, oxide, sulfide, carbonate, and phosphate compounds?
gpt
Hydroxide (OH -), oxide (O 2-), sulfide (S 2-), carbonate (CO3 2-), and phosphate (PO4 3-) compounds are generally not soluble except for those containing sodium (Na +), potassium (K +), ammonium (NH4 +), or barium (Ba 2+).
Explanation: These are specific exceptions to the general rule of insolubility for these types of ionic compounds.
