Q.Hi, I would like to know if there is a faster way to strip silver from a stainless jig than the one I presently use. At the moment I use a mix of 19:1 sulfuric/Nitric @ room Temp. This works (slowly) but now we are finding that we have so much silver work to plate that ...
While these tips won’t remove or reduce existing nitrates in your aquarium, they will stop new nitrates from building up as quickly – which is a good thing! 1. Don’t overfeed your fish! The more your fish eat, the more they are going to poop. And the more they poop, the faster...
Examine the mirror to determine the best way to remove the mirror glass from its frame. In certain types of mirrors, the glass is held within the frame by pliable metal tabs, while in other styles the glass may be secured with screws. Disengage the mirror glass from the frame. Take great...
Q.I called some cleaners to clean my home, which the front view of my house was built with stainless steel but now it has turned to brown colour because of the hydrogen peroxide chemical they used to clean the tiles on the floor. Now what can I use to remove those brown colours from ...
After the oxidation by heating, the solution is neutralized to pH >=3 by adding the alkali. As a result, Pt and Pd in the liquid is precipitated as the hydrate. The precipitate is solid-lipid separated to separate and remove the compound of Pt and Pd from the solution. The recovered ...
Nitric acid, HNO3 Brownell's manganese parkerizing solution. A gel containing phosphoric acid is what is callednaval jelly,a thick gel that can be applied to surfaces to remove rust. Phosphoric acid is also a component of soft drinks leading to lowered bone density. It is also used in dentis...
After soldering, we apply the “pickle” solution, which is a chemical used to remove oxidation caused by firing. Once it’s thoroughly cleaned and dried, we will proceed to clean the edges of the ring from extra material and ensure that the piece is properly soldered. Polish the Ring At...
use known technology to add alkali to precipitate bismuth in the liquid containing chemical impurities, and return the bismuth slag to mix with the crude bismuth oxide raw material and chemically remove impurities , or send it to conventional pyrometallurgy for bismuth ingot recovery; the resulting ...
Filter the precipitated gold from the solution. Rinse the gold with water through the same filter to remove any trace chemicals. The remaining 24K gold precipitate can be dealt with as desired. Most often it will now be melted and cast into a desired form. ...
One way to strip silver plating off copper object is to use nitric acid, which when mixed with the right metal alloys, can give off nitrogen dioxide, which can become deadly. Therefore, only experienced chemists should try to remove plating from metal with the use of chemicals. If you must...
