Sucrose contains both aldose and ketose monomers then why is it non reducing

[@ApekshaChavda-nx9ow]

Bro reducing sugar are those which have free functional group as that of all monosaccharides and disaccharide except sucrose because In sucrose it form glycosidic bond between the aldehyde grp of glucose and ketone grp of fructose as both the groups are now not free it is considered as non reducing sugar❤

Thanks, this video explained what I had accidentally created! I have zero Chem education and am just playing around with a small hot plate _(out of a coffee maker lol),_ and trying to make aqueous metal solutions to see which ones will grow into crystals... ☺️ This, so far, is all very small scale (a few ounce, or about 10-15cc) which has primarily been done using food-grade items like vinegar (5%), NaCl, H2O2 (3%) and maybe 1 or 2 cc of HCl _(? %, by collecting condensation generated from heating a 9.5% gel-based cleaner... 😷). Anyways, how *_I_* accomplished this is slightly different... - I heated ~ 8cc of vinegar, dissolved an unmeasured amount of cane sugar (slightly over saturated I'm sure) - Tossed in an old (1959) copper penny and let it get to work, while the solution maintained roughly 130° F (~54C); occasionally used a syringe to suck up some and spray it onto the penny (high pressure thanks to blunted needle) -- this was working, but not fast enough... 🥴 - After 20 mins and only a slightly teal solution, I started adding H2O2 (3% strength). Total amount, unknown, but the liquid volume was now roughly 50:50. Which at its temperature was now decomposing quite well! - Repeat the syringe procedure a few times, as the penny's surface would rapidly turn dark with oxidation, so spreading it works wash it off and brighten it, before immediately darkening again; - Waited for the solution to cease bubbling (from the H2O2); this coincided with spraying the penny no longer having any effect - Now solution is a much deeper teal color 👍 - Finally, I added powdered Sodium Carbonate ("tetrahydrate" I believe); roughly a Teaspoon worth The solution was still acidic enough to cause a very mild reaction. Stirring it, it slowly began to shift from its clear teal color, to an opaque green, and then slowly gained a faint orange hue. Repeating the syringe method eventually dissolved the sodium carbonate and yielded a rather vibrant orange color that resembled the outside of a Pumpkin. Leaving it to sit overnight and cool off has resulted in a thin layer of "dust" to settle on the bottom of the container, and a deep Red-Orange color! All in all, VERY reminiscent to the video's thumbnail image, but my starting solution (left-most test tube) was not as definitively blue. Don't know if this will crystallize while it evaporates, but here's hoping! 🤞🤞 _(don't worry anyone, I've seen the warnings about the various household items to NOT mix, and the hazards of doing so with other random things ☠️ that's why my "batches" are so tiny!)_
