Q

Copper sulfate crystals experiment method

A
  1. Place some sulfuric acid in a beaker and warm it in a water bath.
  2. Add a spatula of copper(II) oxide powder to the acid and stir with a glass rod.
  3. Continue adding copper(II) oxide powder until it is in excess
    filter the mixture to remove the excess copper(II) oxide.
  4. Pour the filtrate (the copper(II) sulfate solution) into an evaporating basin.
  5. Heat the copper(II) sulfate solution to evaporate half the water.
  6. Pour the solution into an evaporating basin and leave to allow all the water to evaporate.

Q

Copper sulfate crystals experiment: List 3 hazards, their harm and precautions

A

Hazard - Sulfuric acid
Harm - Sulfuric acid is corrosive and damages skin and clothes
Precaution - Wear eye protection and gloves
Hazard - Boiling water bath
Harm - Skin burns
Precaution Ensure the boiling water bath is stable on the gauze
Hot copper(II) sulfate solution spitting out during evaporation
Hazard - Damage to eyes and skin
Harm - Wear eye protection and avoid standing over the hot apparatus

Q

Naming salts

A

The name of a salt has two parts. The first part comes from the metal, metal oxide or metal carbonate. The second part comes from the acid:
hydrochloric acid produces chloride salts
nitric acid produces nitrate salts
sulfuric acid produces sulfate salts
