A method has been developed for dissolving noble metals and metals resistant to hydrochloric acid. This method employs the use of either half-wave or full-wave alternating current electrolysis in hydrochloric acid. The effects of the following variables on the rate of solution were investigated: ...

Ans: Alloys are stronger than the metals from which they are made, more resistant to corrosion, have lower melting point, and have lower electrical conductivity. Solder is an alloy of lead and tin. An amalgam is an alloy of mercury with another metal. Q.10. How do alloys brass ...
It is resistant to corrosion It has good soldering properties Gold Gold alloy is used as the anode, while a thin sheet of pure gold is used as the cathode. The electrolyte used is hydrochloric acid. When electric current passes through the electrolyte, it gets ionised, and the dissolved gold...

(Fig.3a–cand Supplementary Figs.6and22), demonstrating its superior PM recovery performance. S-PAcH(L) also maintained its very highRe(>99%) for all PMs even at 1 M hydrochloric acid (HCl) (corresponding to pH ∼0) (Supplementary Fig.23and Supplementary Note2). Commercial amine ...
Tantalum is the most corrosion-resistant metal in common use today. The presence of a naturally occurring oxide film on the surface of tantalum is the reason for tantalum's extreme corrosion-resistant properties in aggressive media. Its corrosion resistance in sulfuric acid and hydrochloric a...

papyrus combined with zeolite and limestone to remove specific pollutants from water. These plants have not been used in this manner before and so this study will help to determine the efficacy of this combination in removing suspended solids, nutrients, drug-resistant microbial strains, heavy ...
