I think it becomes darker because its molecules get burnt.
After a period of two-three days in citric acid, the aluminium starts to turn black-ish, hence, indicating orrosion.
Do real gold turn black when you burn it
Yes, chlorine does turn sterling silver black!!
because nick is really cool
It's not real. Swarovski doesn't turn black
yes.
because the pressure changes the color when being cooked
The question needs to be more specific. What method of electrolysis are you performing. Are you using aluminum foil and salty water? If you are, the NaCL (salt) will be electrolysed to form NaOH (lye) and also giving off chlorine gas. (which can be dangerous in sufficient quantity) The sodium hydroxide (lye) will in turn attack your aluminum foil creating aluminum oxide. This aluminum oxide it what is causing your water to be murky. Carbon electrodes are a better option.
eggs are acidic. they turn green when you cook them on a aluminum pan. and the pan turns black. it is because of chemical reaction. It also may be over cooked. All eggs become black when you cook them for an extended time.
It will turn aluminum black
it is actually a conductor of heat and electricity. you can check by puting some foil on a piece of toast on a really hot day and if you wait a while it will turn into crispy toast.
Sweet potatoes should not turn black when baking. If you have black spots on the skin (if unpeeled) then you are baking at too high a temperature. To make certain the potatoes are fully cooked, you can boil them first, then wrap them in foil, and bake at 350°F.If they are peeled and turning black, you are still baking at too high a temperature. Try covering the dish with foil, and never bake potatoes over 350°F. Again, boiling them first will help ensure full cooking.
It is a reaction to the baking soda.
Pure aluminium will not. Others will, depending on the composition.
I have never seen foil turn any meat green.
Yeah, but the vectors are activated via RF, remotely. If you turn a humidifier on 100% and wear am aluminum foil lined hat, it will interrupt their reception.
Usually 24 hours and they need to be wrapped and sealed either by a plastic dish or saran wrap--aluminum foil can turn them dark faster--so will air--REFRIGERATE!!!
