- Transition elements
- Compounds that contain a transition element are often coloured
- Copper compunds are often blue
- Iron(II) compounds are often pale green
- Iron(III) compunds are often orange/brown
- Transition elements are often used as catalysts
- Iron is used in the Haber process to make ammonia
- Nickel is used in the manufacture of margarine to harden the oils
- Sodium hydroxide solution reacts with compounds of each transition metal to make a solid of a particular colour
- Copper(II) ions from a blue solid
- Iron(II) ions form a grey/green solid
- Iron(III) ions form an orange/brown gelatinous solid
- These solids are metal hydroxide precipitates
- Compounds that contain a transition element are often coloured
