Asimov Pupil Posted April 12, 2005 Posted April 12, 2005 can someone give a list of some inert metals? much obliged
budullewraagh Posted April 12, 2005 Posted April 12, 2005 well they arent quit inert, but some "inert" metals are: Rh, Pt, Ni, Pd, Au, Ag, Ir, Os
H2SO4 Posted April 12, 2005 Posted April 12, 2005 well they arent quit inert' date=' but some "inert" metals are:Rh, Pt, Ni, Pd, Au, Ag, Ir, Os[/quote'] You should preobaly disclude Ag and Ni. Just my opinion.
budullewraagh Posted April 13, 2005 Posted April 13, 2005 why? ag is less active than, say, Au. Ni isnt very active either
Tetrahedrite Posted April 13, 2005 Posted April 13, 2005 You should preobaly disclude Ag and Ni. Just my opinion. I probably wouldn't include Ag, and most definitely wouldn't include NI.
budullewraagh Posted April 13, 2005 Posted April 13, 2005 i forgot ruthenium. and i guess i'll take back what i asid about nickel
H2SO4 Posted April 13, 2005 Posted April 13, 2005 why? ag is less active than, say, Au. Ni isnt very active either are you on crack. Gold is not more reactive than silver.
Tetrahedrite Posted April 13, 2005 Posted April 13, 2005 I think the answer to this question is best found in nature. I will explain. In this case I would descibe inert metals as those that are found mostly in a native state in the environment. These include Au, Pt, Ir, Os, Pd, Rh, Ru. Metals such as Hg, Ag and Cu are certainly known as native metals, but are more commonly found in an oxidised state. For example both Hg and Ag are commonly found in sulfides (cinnabar, acanthite) and sulfosalts (tetrahedrite for example, see the name; I know what I'm talking about ), and in halides (calomel and chlorargyrite to name but a few). As far as I am aware, Ni is never found on earth as the native metal (except in meteorites) and is almost exclusive found as Ni2+ and very occasionally Ni3+.
jdurg Posted April 13, 2005 Posted April 13, 2005 why? ag is less active than, say, Au. Ni isnt very active either Sorry Budellewraagh, but I have to disagree with you here. Look at ANY activity series or standard reduction potential series and you will find that gold is not as high in the listings as silver is. Silver is by far more active/reactive than gold is.
budullewraagh Posted April 14, 2005 Posted April 14, 2005 i could have sworn i saw silver below gold on the new york regents tables. i checked the potentials though and recognize the greater activity of silver relative to gold
mmalluck Posted April 14, 2005 Posted April 14, 2005 Let me ask you two question. How often do you polish silver? How often do you polish gold?
H2SO4 Posted April 14, 2005 Posted April 14, 2005 silver also tarnishes fairly quick in the presence of sulfur.
5614 Posted April 14, 2005 Posted April 14, 2005 are you on crack. Gold is not more reactive than silver. uh, I don't think so! If in doubt, use google! So search: http://www.google.co.uk/search?hl=en&q=reactivity+series&meta= 1st link -- your wrong 2nd link -- irrelevant 3rd link -- your wrong 4th -- your wrong 5th -- your wrong 6th -- irrelevant 7th -- your wrong etc etc
darth tater Posted April 14, 2005 Posted April 14, 2005 I don't know the symbol, but how about Titanium?
H2SO4 Posted April 14, 2005 Posted April 14, 2005 uh' date=' I don't think so! If in doubt, use google! So search: http://www.google.co.uk/search?hl=en&q=reactivity+series&meta= 1st link -- your wrong 2nd link -- irrelevant 3rd link -- your wrong 4th -- your wrong 5th -- your wrong 6th -- irrelevant 7th -- your wrong etc etc I dont get it why is it so hard for you to understand that silver is more reactive than gold. GOLD IS MORE NOBLE THAN SILVER! Wait, 5614, are you saying what i said is wrong or what budellegraph (or watever ) said is wrong?
akcapr Posted April 14, 2005 Posted April 14, 2005 ya. ALso, what explains the fact that there are alot fewer gold compounds than silver compounds- such as silver nitrate, silver chloride, silver sulfide, silver selenide, silver oxide, silver iodide, etc. you get my point.
jdurg Posted April 15, 2005 Posted April 15, 2005 I dont get it why is it so hard for you to understand that silver is more reactive than gold. GOLD IS MORE NOBLE THAN SILVER! Wait' date=' 5614, are you saying what i said is wrong or what budellegraph (or watever ) said is wrong?[/quote'] He's saying that Bud is wrong. If he's saying that you are wrong, then he should never go anywhere near a chemical as he would obviously not have any clue about chemistry and how to read a table.
H2SO4 Posted April 15, 2005 Posted April 15, 2005 you can get gold oxides, selenides, etc... Yes but they are much harder to create. They can probaly only occur under laboratory conditions. Unlike silver.
budullewraagh Posted April 16, 2005 Posted April 16, 2005 again, the new york state regents is messed up. btw, define "laboratory conditions"
H2SO4 Posted April 16, 2005 Posted April 16, 2005 under heat, pressure, in the presence of a catalyst, ect. I am just saying there mor ethan likely not going to form in nature.
