Test reactivity series Flashcards
What is the reactive series
It is a list of metals in Order of reactivity placing the most reactive metal at the top
Which metal don’t react with oxygen
Silver gold and platinum
When most metals reactive with acid what does it make
Salt and hydrogen gas
Metal +acid —->
—-> salt + hydrogen
Zinc + hydrochloride——>
—-> zinc chloride +hydrogen
List these metals in most to lest reactive - gold potassium magnesium carbon tin platinum hydrogen sodium silver aluminium copper zinc calcium iron lithium
Potassium, sodium , lithium, calcium, magnesium, aluminium, carbon , zinc , iron , tin , hydrogen, copper , silver , gold , platinum
What is oxidation reaction
Metal reacting with oxygen
What does oxidation mean
Gain of oxygen
What metals react with oxygen
All metals apart from silver gold and platinum
When metal react with oxygen gas what solid compound do they make
Metal oxides
Eg copper + oxygen —> copper oxide
What does reduction mean
Loss of oxygen
What type of reaction occurs when aluminium reacts with oxygen
Oxidation
What happens when metals react with cold water
They make alikali solution eg sodium hydroxide and hydrogen gas and they react violently
What does aq stand for
Solution - dissolves in water
What can be observed when metals react with cold water
All fizz of bubble violently as hydrogen gas is made quickly
All float
All turn a universal indicator purple so an alkiali is made
