... I don't believe it is possible to selectivly separate metals using electrolysis. The negative lead attracts positive ions reguardless of any individual...
I was taught in school that it is possible to selectively separate metals by electrolysis. Copper is commercially purified by casting the impure copper which I...
in my research i have dissolved some very insoluable Pd compounds. Use about a 3:2 ratio of ammonia chloride and ammonium chloride at about 1x10^-5 Molar in...
a method to tell if a "silver ring" actually contains surface silver would be through the use of SEM-EDXRA. Energy dispersive x ray analysis allows for the...
... metals by electrolysis. Copper is commercially purified by casting the impure copper which I think would need to be the positive electrode or anode. This...
Roger is correct that these are not good examples because one metal does not go into solution. I don't know of any commercial process where a mixture of ...

Hello, I really want to learn what will occur if iron makes reaction with diute nitric acid and conc. nitric acid. What is the difference of poducts? I know...
I don't usually post anything since there are a lot of knowledgable people on the list. Unfortunately, some statements need to be addressed. Roger stated "I...
... silver stayed in solution." . Roger, I have never seen a solution of silver metal (or any other metal), except for suspensions. Most of the solutions I've...
John answered for the first point. For the second one, phosphines, unlike amines, have fixed configurations around the P atom (no 'flip-flap'). Hence, in their...
The electrochemical separation will be really efficient (this type of separation is always possible, but sometimes too low for industrial purposes, excepted if...
With dil. solution, iron is completely 'killed' (oxidated), as in conc. one, iron is passivated. One could stand this as in the first case the oxidation is...
Hello.. CuCl is relatively unstable on the other hand CuI is stable.Though both being Copper(I).Why? One explanation i have is that Cu(I) is very soft and it...
Dear members, I heard once that When we burn Polythene bags plolythene gases like Dioxins are emitted to make hole in Ozone layer. What reaction actually...
In a closed vessel, in the bottom of which there is some 95% ethyl alcohol, is introduced a drop of a sodium chloride saturated solution, and left at a short...

Dear TKS, I can add alittle to your question. Polyethylene consists of just carbon and hydrogen. Dioxin contains chlorine. Therefore, the chlorine in any...

Is it a test of chemistry? One could think too to radii effect: if we consider Cu+, Cl– and I– as ions, the steric constraints could be favorable to I–,...

We recently did an experiment in my physical chemistry class on heat of solution reactions. In it we measured the temperature change that occurs as varying...
