AI Thread Summary
The discussion centers on the validity of two chemical reactions involving sodium bisulfite (NaHSO3) and zinc. The first reaction, which is cited from Wikipedia, suggests that 2 NaHSO3 and Zn yield Na2S2O4 and Zn(OH)2. The second reaction, found online, proposes that the same reactants, along with sulfurous acid (H2SO3), produce ZnSO3, Na2S2O4, and water. Participants express confusion over the lack of reaction conditions specified in the Wikipedia entry and seek clarification on which reaction is correct. One contributor highlights that the source of the Wikipedia reaction dates back to a 1929 paper, suggesting that further investigation into the original document might provide necessary details. Overall, the thread emphasizes the need for more information on the reaction conditions to determine the accuracy of the reactions presented.

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?

Have you checked what the document (from which the wikipedia reactions is taken) says about reaction conditions?

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.
 

Thread 'Humidity of a saturated NaCl solution with anticaking additive'

I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...

Thread 'Resists for etching Aluminium with NaOH'

I'm trying to find a cheap DIY method to etch holes of various shapes through 0.3mm Aluminium sheet using 5-10% Sodium Hydroxide. The idea is to apply a resist to the Aluminium then selectively ablate it off using a diode laser cutter and then dissolve away the Aluminium using Sodium Hydroxide. By cheap I mean resists costing say £20 in small quantities. The Internet has suggested various resists to try including... Enamel paint (only survived seconds in the NaOH!) Acrylic paint (only...
