1 answer

Here are the solubility classifications for the given chemical formulas based on common solubility rules:

  1. Ca3(PO4)2 - Insoluble
  2. NH4OH - Soluble (ammonium hydroxide, dissociates into NH4+ and OH- ions)
  3. AgNO3 - Soluble (nitrate salts are generally soluble)
  4. BaSO4 - Insoluble (most sulfate salts are soluble, but barium sulfate is an exception)

To summarize:

  • Ca3(PO4)2 - Insoluble
  • NH4OH - Soluble
  • AgNO3 - Soluble
  • BaSO4 - Insoluble
