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?
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
Do the published values of Enthalpy include the work done against a constant pressure, e.g., the atmosphere? (I am not a chemist). I am reviewing enthalpy and entropy as part of the statistical mechanics applied to transistors. I assume, from my reading, that the work done would mostly apply to reactions involving gasses.
It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert?
What is so special with a full p orbital?
Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive.
Can someone explain it to me?
Thanks!!
