Topic 4 Reactivity series Flashcards
What is reactivity series
Lists metals in order of there reactivity
What determines how reactive metals are
How easily they lose electrons - forming positive ions
The higher the reactivity the easier it is for them to form positive ions
The higher the metal the more easily it reacts with …
Acids ir water
The order of reactivity
Potassium
Sodium
Lithium
Calcium
Magnesium
Carbon
Zinc
Iron
Hydrogen
Copper
Between potassium and calcium how reactive are the metals
Very reactive
Between magnesium and iron how reactive are the metals
Fairly reactive
How reactive are hydrogen and copper
Not very reactive
What is the speed of reaction indicated by
The rate ate which bubbles of hydrogen are given off
Acid + metal ->
Salt + hydrogen
The more reactive the metal
The faster the reaction
How can you also investigate reactivity of a metal
Measure the temperature change of the reaction with an acid or water over a set period of time
If you use the same mass and surface area each time the more reactive the metal the greater the temperature change
Metal + water ->
Metal hydroxide +hydrogen
Which metals react with water
Potassium
sodium
lithium
calcium
Which metals won’t react with water
Zinc
Iron
Copper
