earlier when I was metal detecting I found a sterling silver ring band, it is tarnished and I can't afford to go out and buy tarnish remover stuff, is there anything around the house that I could try using?
that's an oxidation help reaction it ought to be belanced has one so first you may desire to calculate the oxidation numbers (o.n.) of the species: eq: Al(s) + HCl ? H2 (g) + AlCl3 o.n.: 0.+a million -a million .0+3 -a million The oxidation style of H differences of +a million to 0 so its a help reactionThe oxidation style of Al differences of 0 to +3 so its a oxidation reactioncalculate the balanced equation (Al(s) ? AlCl3 + 3e-) x 2 (2e- + 2HCl ? H2) x 3 -2Al(s) + 6HCl ? + 2AlCl3 + 3 H2
For this experiment you will need: a tarnished piece of silver a pan or dish large enough to completely immerse the silver in aluminum foil to cover the bottom of the pan enough water to fill the pan a vessel in which to heat the water hot pads or kitchen mitts with which to handle the heated water vessel baking soda, about 1 cup per gallon of water Line the bottom of the pan with aluminum foilSet the silver object on top of the aluminum foilMake sure the silver touches the aluminum Heat the water to boilingRemove it from the heat and place it in a sinkTo the hot water, add about one cup of baking soda for each gallon of water(If you need only half a gallon of water, use half a cup of baking soda.) The mixture will froth a bit and may spill over; this is why you put it in the sink Pour the hot baking soda and water mixture into the pan, and completely cover the silver Almost immediately, the tarnish will begin to disappearIf the silver is only lightly tarnished, all of the tarnish will disappear within several minutesIf the silver is badly tarnished, you may need to reheat the baking soda and water mixture, and give the silver several treatments to remove all of the tarnish.
