Document Summary

Tomorrow is valentine"s day a day created by card companies and florists . Practice ps #5 can solve q 1 7. What is soluble and what is not. In pure water or with a common ion. Substances with similar types and magnitude of intermolecular forces will likely dissolve in each other. Process can be viewed occurring in 3 steps. Step 2 overcome intermolecular forces in the solvent to make room for the solute. Step 3 interaction of the solute and the solvent to form a homogeneous solution. Precipitation when and how much solid will precipitate out of solution. Cl, br and i salts are soluble except agx, hg2x2 and. So4 salts are soluble except baso4, srso4, pbso4, (caso4,ag2so4 slightly soluble) Oh salts are mostly insoluble except group 1, nh4, slightly ba(oh)2 and sr(oh)2. Most co3, po4 and s salts are insoluble except group 1 and nh4. Ag3po4 (s) 3 ag+ (aq) + po4.
