C5 Flashcards
What is the reactivity series?
It is the list of metals in order of their reactivity with the most reactive metals at the top and the least at the bottom
How to see how reactive the metal is?
You can order some metals on reactivity by seeing their reactions with water so you can order all of group 1 metals.
How do you tell if metals react with water or dilute acids?
It would produce hydrogen gas and would be detected by a ‘pop’ with a lighted spill.
What is a displacement reaction?
When a more reactive metal displaces a less reactive metal from an aqueous solution of one if its salts.
What is an ionic equation?
It shows only the atoms and ions that change in a reaction.
How to remember the reactivity series?
Please stop calling me a careless zebra, instead try learning how copper saves gold platinum
What is reduction?
When something gains electrons and loses oxygen.
What is oxidisation?
When something loses electrons and gains oxygen.
Why and how are carbon and hydrogen in the reactivity series?
They can be given positions in the reactivity series due to the basis of displacement reactions using them.
What does a half equation show?
It shows what happens to each reactant in terms of if they gained or lost electrons.
What is a metal ore?
It contains enough of the metal to make it economic to extract the metal. They are mined and may need to be concentrated before the metal is extracted and purified.
How can you tell if it is worth extracting a metal?
How easy it is to extract it from the ore, how much metal the ore contains and the changing demands for a particular metal.
How can you tell how to extract a metal from its ore?
Through the reactivity series, where the oxides of metals below carbon in the series can be reduced by caron to give the metal element. However metals more reactive that carbon cannot be extracted from their ore using carbon. They are extracted by electrolysis of the molten metal compound.
What do you get when you react a metal and an acid?
A salt and hydrogen (MASH)
What is a redox reaction?
A reaction between a metal and an acid. The metal atoms lose electrons and are oxidised and hydrogen ions from the atom gain electrons and are reduces.
