  1. Net Ionic Equations Problems

  2. Solubility rules • Rules to determine if something is soluble (will stay dissolved--aq--) or when it is insoluble (will precipitate out, become a solid--s--) • You will be able to use the solubility rules sheet on the test.

  3. Soluble Compounds • All common compounds of Group I are soluble except LiF, Li2S, and Cs2S. • All ammonium (NH4) compounds are soluble. • All acetates (CH3COO) are soluble except Fe3+ • All nitrates (NO3), and chlorates (ClO3) are soluble.

  4. Soluble Compounds cont. • All binary compounds of the halogens (other than F) with metals are soluble, except those of Silver, Mercury(I), and Lead. Pb halides are soluble in hot water. • All sulfates are soluble, except those of barium, strontium, calcium, lead, silver, and mercury (I). The latter three are slightly soluble.

  5. Insoluble Compounds • Except for rule 1 and 2, carbonates, oxalates, sulfites, chromates, oxides, silicates, and phosphates are insoluble. • Except for rule 1 and 2 hydroxides are insoluble except Ba, Sr, and Ca • Except for rule 1 and 2, Sulfides are insoluble except for calcium, barium, strontium, magnesium.

  6. K3N K2CrO4 Na2CO3 BaSO3 Li2S (NH4)3PO4 NH4NO3 FeSiO3 Mg(NO3)2 CuO AgClO3 NaOH AgCl BaOH CuF2 Ni(OH)2 CrSO4 MgS CaSO4 BeS (aq) (aq) (aq) (s) (s) (aq) (aq) (s) (aq) (s) (aq) (aq) (s) (aq) (s) (s) (aq) (aq) (s) (s) Examples

  7. Net Ionic Equations • Identify what is soluble or insoluble and write the net ionic equation • Ca(NO3)2 + Na2CO3 → NaNO3 + CaCO3 • Ca2+ (aq) + CO32-(aq) → Ca(CO3) (s) • Fe(ClO3)2 + NaCH3COO → NaClO3 + Fe(CH3COO)2 • No net ionic equation • Pb(NO3)4 + (NH4)2SO4 → Pb(SO4)2 + NH4NO3 • Pb4+ (aq) + 2 SO42-(aq) → Pb(SO4)2 (s)

  8. Homework • Determine what is soluble and insoluble and write the net ionic equation • Ca(ClO3)2 + Na2CO3→ CaCO3 + NaClO3
