5. Write the formula of each compound. Based on the formula, identify the compounds as ionic or covalent. For each ionic compound, check the solubility rules (below) and record the predicted solubility here. Use ChemSpider or other reference to look up the missing melting points (°C) and add those to the table. insoluble (s) mostly soluble (aq) mostly formula 1. NHẠC 2G7 HG 0₂ 3. CaCO3 4. CUSDA 5. P₁₂(NO₂)2 7. C18H123₂60₂ 8. CHAN20 LC12H240₂ Ionic or Covalent? Hydroxide: OH lonic Covalent ionic lons Group I ions: Li, Na, K, etc. Ammonium: NH₂ Nitrate & Nitrite: NO₂, NO₂ Halides: Ct, Br, I Sulfate: SO Carbonate: CO² For ionic cmpds only: predicted solubility yes all ammonium salts are soluble Soluble with all anions. Soluble with all cations. melting point Sublimes at 340°C Abbreviated Solubility Guidelines for Aqueous Solutions 110°C decomposes (loss of water) anhydrous salt melts at 560°C 185-190°C 31 Soluble with all cations, EXCEPT Ag", Pb, Hg Hg is moderately soluble"; I is insoluble with heavy metals. Most are soluble, EXCEPT Ag, Pb, Ca, Ba, Hg Hr & Srare moderately soluble Soluble only with Group IA elements and NH Soluble only with Group IA elements and Ba Ca & Srare slightly soluble.
