Is the Synthesis of Sodium Dithionite Accurate?

[asamaid1]

is the following reaction right?

2 NaHSO3 + Zn → Na2S2O4 + Zn(OH)2

because i tried this reaction but i m not getting any Na2S2O4. I got this reaction in wikipedia. And i found another reaction in the net which is following:

2 NaHSO3 + H2SO3 + Zn ─→ ZnSO3 + Na2S2O4 + 2 H2O

Which one is right? Plz anyone can help me?

Sorry, I can't help you - but I am rather surprised by your statement. The document I fetched, while incomplete, says a lot about how this reaction is performed.

Really, where did u get that. I did find some information about the second reaction, but that is confusing. I did not find any information about the first. If u got any information please help me with that. I need that for my project. Thanks.

Have you checked the references? The equation is listed as coming for a paper published in 1929, and there is a link to this paper.
