metals and transition metals

Question 1

Properties and uses of iron and steel

Answer 1

PROPERTIES
Iron: good conductor, can be magnetised
High carbon steel: hard, very strong, potentially brittle
low carbon steel: malleable, strong and tough but vulnerable to corrosion
stainless steel: very resistant to corrosion
USES
Iron: magnets, transformer cores
High carbon steel : railway tracks
Low carbon steel: car parts
stainless steel: cutlery

Question 2

Properties and uses of aluminium

Answer 2

Properties: strong, lightweight, good conductor, resistant to corrosion
Uses: Food and drink cans, saucepans

Question 3

Properties and uses of copper

Answer 3

Properties: ductile, good conductor, unreactive
Uses: wires, pipes

Question 4

Properties and uses of titanium

Answer 4

properties: High melting point, resistant to corrosion, strong, hard
Uses- jet engine parts, medical implants

Question 5

What is steel

Answer 5

Iron produced from the blast furnace contains high amounts of carbon which makes it brittle. Remove this carbon and it becomes steel
3 kinds of steel
Mild steel- easily shaped and used for car parts
High carbon- very hard and used in drills, hammers and tools
stainless- corrosion resistant, strong used in cutlery

Question 6

What are transition metals

Answer 6

Transition metals have the following properties:
- malleable
- form distinct colours
-conductors
- many variations such as Fe3+ or Fe2+
-catalysts
- lower reactivity than group 1 and 2
Precipitates formed with NaOH
fe2+ forms green
Fe3+ forms brown/ orange
Cu2+ forms blue
