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 'How to make Sodium Chlorate by Electrolysis of salt water?'
I have a power supply for electrolysis of salt water brine, variable 3v to 6v up to 30 amps. Cathode is stainless steel, anode is carbon rods. Carbon rod surface area 42" sq. the Stainless steel cathode should be 21" sq. Salt is pure 100% salt dissolved into distilled water. I have been making saturated salt wrong. Today I learn saturated salt is, dissolve pure salt into 150°f water cool to 100°f pour into the 2 gallon brine tank. I find conflicting information about brine tank...
