What else can I help you with?
Can pt and pd be used in the hydrogenation of alkenes?
Yes, both platinum (Pt) and palladium (Pd) can be used as catalysts in the hydrogenation of alkenes. These metals are often used in heterogeneous catalysis to facilitate the addition of hydrogen to alkenes, leading to the formation of alkanes.
What elements can be found in elemental form uncombined with other elements on earth?
Highly unreactive elements that will not chemically combine include: Platinum (Pt) Gold (Au) Helium (He) Argon (Ar) Krypton (Xe) Neon (Ne) The first two are unreactive because they are at the bottom of the metals reactivity series. The rest are unreactive because they are part of the inert gases.
What is the chemical symbol for potassium Na K Pt or O?
Symbols are as follows: Na for sodium K for potassium Pt for platinum O for oxygen
List of non metals with their symbols?
1. Palladium- Pd 2. Argentum- Ag 3. Platinum- Pt 4. Aurum- Au 5. Mercury- Hg 6. Ruthenium- Ru 7. Rhonduum- Rh 8. Osmium- Os 9. Iridium- Ir 10. Rhenium- Re
How do you assay for platinum and rhodium?
The answer to your question depends in part on the form of the sample requiring analysis. There are two general forms in which refined Rhodium and / or Platinum may be found - as an alloy of Pt/Rh or in the form of a mixture of the ions of Platinum and / or Rhodium. The former is how one may encounter Platinum Rhodium mixtures in thermocouple wires, or in furnace elements intended for specific high temperature applications. For simple metals and their alloys sequential digestion into acids may be the preferred method of generating an initial sample for further analysis. The information obtained should be sufficient to determine the relative proportions of Pt : Rh within a percent. For plating solutions, it is presumed that the Platinum and Rhodium values are simultaneously present in solution. In either of the cases cited a reasonable approach would be to subject the dissolved metals to Inductively Coupled Plasma analysis. A benefit of this approach is that the two metals may be simultaneously analyzed and their relative proportions quantified. Moreoever, as ICP is a very sensitive method, the quantity of sample sacrificed to this procedure is small. To conduct sequential digestion into acid the intrinsic properties of the metals can form a guide. http://www.britannica.com/eb/article-9063458/rhodium Platinum is readily dissolved by Aqua Regia (a specific mixture of concentrated Nitric and Hydrochloric acids) but Rhodium remains unaffected by this mixture. Meanwhile Rhodium is susceptible to dissolution in Sulfuric Acid - in which Platinum would remain undissolved. Thus, one might contemplate taking a Pt/Rh alloy, dissolving the Platinum metal with Aqua Regia, then removing the Platinum rich solution. The remaining solids could then be treated with Sulfuric Acid to dissolve the remaining Rhodium. Dilution of the respective solutions could permit sequential assay for the two metals by ICP. Because each solution uses concentrated acids it is imperative that they be diluted by addition of the solution to water, rather than water to the acid extracts. For plating solutions, the Pt/Rh mixtures may be directly and simultaneously assayed after dilution to the range of detection, by ICP. For the most accurate analyses of Pt and Rh in more complex matrices classical approaches are generally prefered, often beginning with a fire assay. This method is also the preferred approach to assaying ore bodies or minerals that contain traces of the Platinum group metals. http://www.britannica.com/eb/article-81568/platinum-group A description of Fire Assay methods is found here: http://www.mine-engineer.com/mining/assay2.htm
Is Plantinum Pt Alkali Alkaline-Earth Or Transition?
Platinum is a transition metal. It is in the d block.
Why metals like Au or Pt do not react with oxygen directly?
Au or Pt are highly stable and they are noble metals as they do not react with oxygen readily
Which metals do not react with dilute acid to produce hydrogen?
For example metals as Pt, Au, Os and other.
What types of metals are measured in avoirdupois ounces?
Generally precious metals as Au, Ag, Pt, Pd, Ir.
Name metals which do not react with oxygen?
Au and Pt are some metals which do not react with O.
Which metals don't react with water but react with oxygen?
Beryllium is the only alkaline metal that reacts to oxygen but not to water. The hydrogen in water stabilizes the reaction.
How do you make a periodic table out of Skittles?
you can't really. But if you need to then you can take the different kinds of skittle colors and make them in the shape of the PT (periodic table) and the sort the colors into alkaline metals, alkaline metals, metalloids, nonmetals, noble gases, transition metals, and inner transition metals. I would reccomend looking at a periodic table with color first.
What are some non reactive metals?
There is no "group" of metals that are unreactive. However, metals that are low on the reactivity series are unreactive. Examples: Gold, Silver, Titanium The Noble gasses are a group on the periodic table that are largely unreactive.
What is platinum's family name?
AnswerIt is a transitional metal in period 6, group 10 of the periodic table.
Which PT blocks contain only metals?
Transition metals (Blocks 3-12) contain only metals. This includes the groups known as d-block (3-12) and f-block (lanthanides and actinides).
Which group of metals is so reactive than its members are never found uncombined in nature?
For example platinum group of metals: Pt, Ir, Os, Pd, Rh, Ru.
What is plantinum?
Platinum is one of three precious metals. It is a metallic element with the atomic number 78 and the symbol Pt.
