What’s the first solubility rule?
If it contains an Alkali Metal (ion from Group 1A), it’s soluble!
What’s the second solubility rule?
The salt is soluble if it contains: • Ammonium (NH4+) • Acetate (C2H3O2-) • Nitrate (NO3-) • Chlorate (CLO3-) • Perchlorate (CLO4-) Hint: Ammy Aces Nightly Coloring, Perched.
What’s the third solubility rule?
It is soluble if it contains • Bromide (Br-) • Chloride (Cl-) • Iodide (I-) EXCEPT when with • Ag+ , Pb2+ , or Hg22+ Hint: sol-Bros Clasp Intensely EXCEPT for Agressive Public Hugging
What’s the fourth solubility rule?
The salt is soluble if it contains sulfate (SO42-) EXCEPT when with Sr2+, Ca2+, Ba2+, Pb2+, Hg22+ Hint: soluble Soulmate - Sr. CaBa Public Hugging
What are the two insolubility rules?
INSOLUBLE: • All metal hydroxides (OH-) and metal oxides (O2-) • EXCEPT those of Group 1A, Ca2+, Sr2+, Ba2+ (the ions of the strong bases) • All salts that contain phosphate (PO43-), carbonate (CO32-), sulfite (SO32-), and sulfide (S2-) • Hint: insoluble Pho is a Carby Soup Soup. Only time ite appears. • EXCEPT if there is a Group 1A ion, or NH4+ (per the solubility rules)
Describe the trend for solubility of molecular compounds.
• We learned the solubility rules for ionic compounds. • Totally different for molecular compounds. They are more soluble (dissolve) if they are more polarizable (bigger). • Ex: Can dissolve more O2 than N2 in water. • They will dissolve, not dissociate.
