C5.2 - Displacement Reactions (Finished) Flashcards
A ___ reactive metal will ___ a ___ reactive one from a solution of one of its ___
More, displace, less, salts
What will happen when magnesium and copper(II) sulfate react?
Magnesium is more reactive than copper so the copper ions will be displaced from the solution to form copper metal Cu and the magnesium metal forms aqueous ions Mg 2+ and dissolves into the solution of the salt to make magnesium sulfate
What is shown by an ionic equation?
The atoms and ions that change in a reaction. Any that stay the same do not appear in the ionic equation
Turn Mg + CuSo4 -> MgSO4 + Cu into an ionic equation?
Mg(s) + Cu2+(aq) -> Mg2+(aq) + Cu(s)
Why can the non-metals carbon and hydrogen be given positions in the reactivity series?
On the basis of displacement reactions
What can carbon be ised for?(displacement)
In the extraction of metals from their oxides trough displacement reactions
What is the limitation of using carbon to separate metals from their oxides?
It can only be done for metals below aluminium in the periodic table as it is less reactive than it
What does OILRIG mean?
Oxidation is loss (of electrons)
Reaction is gain (of electrons)
What is oxidation and reduction?
Oxidation is the loss of electrons
Reduction is the gain of electrons
What are the two half-equations for the displacement of copper(II) ions by iron? (Fe(s) + Cu2+(aq) -> Fe2-(aq) + Cu(s))
Fe(s) -> Fe2+(aq) + 2e-
Cu2+(aq) + 2e- -> Cu(s)

Okok
What will metals produce when reacting with acids?
A salt and hydrogen gas
How can you find the order of reactivity of metals?
Using displacement reactions. Also observing their reactions with water and dilute acid
