Sodium + Water →Sodium Hydroxide + Hydrogen
Metal + Acid →Metal Salt + Hydrogen
Zinc + Sulfuric Acid →Zinc Sulfate + Hydrogen
What Salt is Produced from a metal reacting with hydrochloric acid?Chloride Salt
What salt is produced from reacting a metal with sulfuric acid?Sulfate Salt
What salt is produced from a metal reacting with nitric acid?Nitrate Salt
Name the metals stored under oilPotassium, Sodium, Lithium
What metals react with acid but not waterAny metals between aluminium and lead in the electrochemical series
Describe the test for hydrogen gasTest hydrogen gas with a lighted splint and it will go pop.
What is a metal ore?A rock containing a naturally occurring metal compound.
Name two metal compounds that decompose on heating to produce the metalSilver oxide, mercury oxide
What oxides are extracted by heating with carbon?Any oxides from zinc oxide to lead oxide in the electrochemical series
What metals are extracted from their oxides by electrolysisAny from Lithium oxide to aluminium oxide in the electrochemical series.
Name the metal extracted in a blast furnaceIron
What happens in a displacement reaction and what would you observe?When metals higher up in the reactivity series displace those lower down from solution you see the metal changing colour in a displacement reaction.
Write a word equation for magnesium displacing zinc from zinc sulfate solutionMagnesium + Zinc Sulfate → Magnesium sulfate + Zinc
What metals could displace iron from solution?Any metals above iron in the electrochemical series
What is corrosionA chemical reaction in which the surface of a metal changes into a compound from an element.
What are the two conditions required for rusting?Oxygen and water
Describe the test for rustFerroxyl indicator changes colour from yellow to blue in the presence of rust.
Give the definition of galvanisingCoating iron in zinc
Why does galvanising protect iron from rusting?It stops air and water reaching the iron. If scratched it corrodes instead of the iron and provides sacrificial protection
What is meant by sacrificial protection?Connecting a metal above iron in the electrochemical series to slow the corrosion of iron. The higher up metal is sacrificed to protect the iron.
What metals could be used to protect iron from rusting by providing sacrificial protection?Any metal higher than iron in the electrochemical series, usually magnesium, aluminium or zinc.
Can potassium, sodium or lithium be used for sacrificial protection?No, as they are far too reactive and unstable in air.
What metals react with water, acid and oxygen?Lithium, Potassium, Sodium, Magnesium
What metals react with oxygen and acid only?Aluminium, zinc, iron, nickel, tin, lead
What metals react with only oxygen?Copper, silver, mercury
What metal is completely unreactive with water, oxygen and acid?Gold
List the reactivity series in orderLithium, potassium, sodium, magnesium, aluminium, zinc, iron, nickel, tin, lead, copper, silver, mercury, gold.
