  8. 8. Soluble or Insoluble?Soluble Compounds Insoluble CompoundsAll salts of Group I elementsAll nitratesAll ammonium saltsMost chlorides, bromides and iodides Chlorides, bromides and iodides of silver and leadMost sulfates Sulfates of calcium, barium and leadGroup I hydroxides and carbonates Most hydroxides and carbonatesare soluble (calcium hydroxide isslightly soluble)Group I and II oxides react with water Most metal oxides
  9. 9. Soluble or Insoluble?• Potassium bromide• Silver bromide• Sodium hydroxide• Calcium sulfate• Lead iodide
  10. 10. How will you prepare ZnSO4? Since ZnSO4 is a soluble salt (Note: Mostsulphates are soluble), I can use reaction withacid, base or carbonate or titration. If I haveavailable acid and metal then I can do thatinstead of titration. I will then mix zinc powderwith sulphuric acid until no effervescence ispresent. I will then filter it, collect the filtrateand crystallise it. Once I reach a saturatedsolution, I will let it cool. I will then wash it withdistilled water to remove impurities and thendry it on filter paper.
  11. 11. How will you prepare these salts? • CuSO4 (Jorge & Holly) • CaCl (Satu & Alicia) • K2SO4 (Rizal & Vanessa) • PbCl2 (Zaynab & Reem)
