Making Soluble Salts (using metal/insoluble base)

If you're making a salt, you need to know if it's soluble or not so you know what method to use
1. Most chloride, sulfates and nitrates are soluble in water (excpetion is lead choride,sulfate and silver chloride)
2. Most oxides, hydroxides are insoluble in water
Making soluble salts using a metal or an insoluble base
1. 1. You need to pick the right acid, plus metal/insoluble base (metal oxide/hydroxide)
  1. e.g. if you want to make copper chloride mix HCL acid and Copper oxide
2. 2. You add the metal, metal oxide/hydroxide to the acid - the solid will dissolve in the acid as it reacrs. You'll know when the acid has been neutralised because the excess solid will sink to the bottom of the flask.
  1. 3. Filter out excess metal, metal xide or hydroxide to get the salt solution. To get pure, solid crystals of salt, evaportae the water (make solution more concentrated) and leave rest to evaportae slowly. CRYTSALISTAION!
