Required Practical 1: Making Soluble Salts

• equipment for the practical

  beaker,gauze,tripod,heatproof mat,Bunsen Burner
• what is the first step

  start with a fixed volume of dilute sulfuric acid this is our limiting reactant
• what is the second step

  Gently heat the acid until almost burning
• what is the second step

  Use a spatula to add small amounts of copper oxide to the acid and then stir The copper oxide will react+seem to disappear
• what is the third step

  continue adding copper oxide if the solution continues to be clear blue.Stop adding copper oxide if some powder remains after stirring
• what is the result of the stirring

  the reaction has stopped.all of the acid has reacted.
• fourth step of the practical

  use filtration to remove the unreacted copper oxide
• Final stage of the practical

  place the solution in an evaporating basin Heat gently over a beaker of boiling water Heat until around half of the solution remains
• dry crystals

  leave the solution for 24 hours in a cool place for crystals to form.Scrape crystals onto paper towel+gently pat them dry
