Sulfuric Acid as a Dehydrating Agent

• Why is concentrated sulfuric acid a dehydrating agent?

  It removes water from a substance
• When is sulfuric acid used as a dehydrating agent?

  In glucose

  With hydrated copper (II) sulfate
• What happens when sulfuric acid is use in glucose?

  It removes 6 water molecules per glucose meaning only carbon is left over
• What equation represents the process of sulfuric acid in glucose?

  C6H12O6 -> 6C + 6H2O
• What are the observations when sulfuric acid is used as a dehydrating agent in glucose?

  Exothermic Reaction - Water molecules are released as steam and a black mass of carbon forms
• What happens when sulfuric acid is used as a dehydrating agent in hydrated copper (II) sulfate?

  Water is removed, forming anhydrous copper (II) sulfate
• What does anhydrous copper (II) sulfate look like?

  White powder
