Will magnesium react with sodium sulfate?

1 Answer

No reaction will occur because Mg is less reactive than Na.


A single-replacement reaction would need to occur for #"Mg"(s)# to react with #"Na"_2"SO"_4(aq)#. When the metal is higher in the activity series (see below), it is more easily oxidized.

With your question this is not the case for sodium, as it is higher than magnesium and so it would rather NOT be reduced; thus, nothing will take effect.
