Solubility Rules and

Sweet Sixteen

By Tori Baggstrom and Jen Bergamotto


You’re Invited!

  • Who: Tori and Jen

  • What: Sweet Sixteen Solubility Tournament

  • When: June 4, 2007

  • Where: Voorhees High School

  • Why: Because Chemistry’s the Best

  • RSVP: 1-800-CHEMISTRY


Solubility Rules/Facts

  • All common salts of group 1 and Ammonium (NH4+) are soluble

  • All Nitrates (NO3-) and Acetates (C2H3O2-)

  • Binary Compounds with Group 7 are except silver, Lead, Mercury

  • Sulfates except Barium, strontium, calcium, silver, mercury, and lead

  • Except for Rule 1, carbonates, hydroxides, oxide, sulfide, phosphate are not soluble

    Fact: If a compound is not soluble then it forms a solid and precipitates.
