Reactions Of Metals And Acids Flashcards
What does reactivity mean?
How vigorously a chemical reacts
How can metals be ordered by reactivity
Comparing their reactions with water and acid
Name given to list of metals ordered by reactivity
Reactivity series
Why are gold and silver found naturally in the earths crust
They are very unreactive
What’s an ore
Valuable rock containing a metal compound
How are metals less reactive than carbon extracted from their ores
reduction with carbon
How are metals more reactive than carbon extracted
Electrolysis
What do oxidation and reduction mean
Oxidation is the addition of oxygen
Reduction is the removal of oxygen
What is made when copper carbonate decomposes
Copper oxide and carbon dioxide
What is a displacement reaction
When a more reactive substance replaces a less reactive one in a compound
In terms of PH what is an acid
A solution with a ph of less than 7
Terms of ph what’s an alkali
A solution with a ph of more than 7
In terms of ph what’s a neutral solution
A solution with a ph of exactly 7
How can you measure the ph of a solution
An indicator or pH probe

Nitric acid HNO3
Hydrochloric acid HCL
Salts formed from hydrochloric, sulfuric and nitric acid
Chloride, sulfate and nitrate
Metal and acid
Salt and hydrogen

salt and water
What is a base
A substance that reacts with acids in neutralization reactions
What is an alkali
A base that dissolves in water to for a solution with a PH above 7
Metal hydroxide and acid
Salt and water
Metal carbonate and acid
Salt and water and carbon dioxide
What is a neutralization reaction
A reaction between an acid and a base to produce water
