Quantitative test for sulfur dioxide in orange juice

AI Thread Summary
A quantitative test for sulfur dioxide in orange juice can be performed using titration. The procedure involves heating the sample with hydrochloric acid (H+) while nitrogen gas (N2) bubbles through the mixture. The sulfur dioxide gas produced is then collected in a separate flask containing hydrogen peroxide. The resulting solution is subsequently titrated with sodium hydroxide (NaOH) to determine the concentration of sulfur dioxide. Additional resources or links for detailed procedures may be helpful for those seeking more information.

Is there a quantitative test for the amount of sulfur dioxide in orange juice. Nothing too complicated, I am only in year 11. Can it be done using titration?
 
Chemistry news on Phys.org
yes, although i can't remember the corrrect procedure from top of my head. It goes something like this, Sample is heated(with H+) with N2 bubbling thru the mixture, the gas produced is collected in a separate flask with hydrogen peroxide and the subsequent solution is titrated with NaOH.
 
anyone care to elaborate? a link maybe? i seem to be having trouble finding anything with google. many thanks in advance
 

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...
