listen guys i know how to search in google.
With that question i mean
is the Na2SO5 a weaker precipitant than Na2SO4?

 

[Geo]

sodium sulfite will precipitate gold and sodium sulfate will not.

if you are looking for a precipitant, just keep that in mind. sodium sulfate will just make a mess.

Sorry, but initially, you did not gave the context of which you ask your question... how are we to know what it is you really asking...?

As Geo said:
SO3^-2 (Sulfite) - Is a reducing agents.
SO4^-2 (Sulfate) - Nither reducing or oxidising.
SO5^-2 (PerSulfate) - Is an Oxidising agent.
