Reactivity Series Flashcards
Reactivity series
Potassium, sodium, lithium, calcium, magnesium, aluminium, carbon, zinc, iron, hydrogen, copper, silver, gold
What a reactive acid is added to a dilute acid, a ………. forms.
salt
How can you determine the name of a salt formed?
The first part of the name of the salt comes from the name of the metal and the second part is from the acid.
What salts do these acids form?
a) hydrochloric
b) sulphuric
c) nitric
a) chloride
b) sulphate
c) nitrate
What is a displacement reaction?
Displacement reactions involve a metal and a compound of a different metal. In a displacement reaction, a more reactive element takes the place of a less reactive element (leaving it pure and uncombined)
What does magnesium and copper sulphate form? Is this a displacement reaction and why?
Magnesium (s) + copper sulphate (aq) —> magnesium sulphate (aq) + copper (s)
Yes, it is a displacement reaction because magnesium displaces copper (because it is more reactive).
What colour are the following sulphates at room temperature?
a) magnesium sulphate
b) zinc sulphate
c) copper (III) sulphate
d) iron (II) sulphate
a) colourless
b) colourless
c) blue
d) green
What colour are these metals at room temperature?
a) magnesium
b) zinc
c) copper
d) iron
a) grey
b) grey
c) pink-brown
d) grey
Why can there be no reaction between magnesium and magnesium sulphate?
It can’t displace itself.
What is oxidation?
Oxidation is the gain of oxygen.
What is reduction?
Reduction is a the loss of oxygen.
What is a redox reaction?
A redox reaction is a reaction in which both oxidation and reduction occur.
What is oxidation/reduction in terms of electron loss/gain.
OIL RIG
Oxidation - loss of electrons
Reduction - gain of electrons
What is an oxidising agent?
An oxidising agent causes another substance to be oxidised. In the process it is reduced.
What is a reducing agent?
A reducing agent causes another substance to be reduced. In the process it is oxidised.
