Salts

• What is the process of making insoluble salts called?

  Precipitation reactions
• Why is lead chloride described as an intolerable salt?

  It does not behave like other salts
• What are two reactants to form barium sulfate?

  Barium chloride and sulfuric acid
• Is potassium chloride soluble or insoluble?

  Soluble
• Is copper carbonate soluble or insoluble?

  Insoluble
• Is calcium sulfate soluble or insoluble?

  Partially soluble
• Is magnesium hydroxide soluble or insoluble?

  Insoluble
• What is the method for making soluble salts using acid and alkali reactions?

  1. Measure acid into a conical flask.
  2. Add indicator drops.
  3. Slowly add alkali until neutralization.
  4. Repeat without indicator for purity.
  5. Evaporate water and crystallize.
• What should you do after the reaction is complete to obtain pure salt?

  Evaporate off some water
• What remains in the solution after the reaction is complete?

  Only the salt and water
• How can you make a pure sample of iron nitrate?

  Use iron and nitric acid
• What happens to the solution after crystallization?

  It is filtered and dried
• What is the significance of using no indicator in the final reaction?

  To prevent contamination of the salt
