Journals & Books; Help In the case of chlorine reduction on platinum, the results indicate that adsorption of chlorine molecules with a subsequent rate determining electrochemical adsorption step is the dominant mechanism.

The exchange current density seems to decrease linearly with the logarithm of the amount of surface oxide.

Platinum is a member of the group of six platinum metals which occur together in nature and is located in the center of the Periodic Table in the Iron–Cobalt–Nickel group: Fe Co Ni Ru Rh Pd Os Ir. Platinum (Pt), a transition metal, was well-known in South America by metalworkers, long before Christopher Columbus crossed the Atlantic.

Platinum was used in jewelry and ornaments, and valued because it did not tarnish like silver. The Spanish called this white metal platina, or little silver. Readers examine the many applications of platinum in industry, including its use as a catalyst in Reviews: 1.

The absence of platinum was the only change in reaction variables between these two experiments, and it is feasible that the gaseous platinum chloride which penetrated the carbon layers (along with the chlorine gas) deposited and/or catalyzed the reaction at the SiC/carbon layer reaction interface, effectively activating the entire surface for Cited by: Voltammetry is reported for chlorine, Cl2, dissolved in various room temperature ionic liquids using platinum microdisk electrodes.

A single reductive voltammetric wave is seen and attributed to the two-electron reduction of chlorine to chloride.

Studies of the effect of voltage scan rate reveal uniquely unusual behavior in which the magnitude of the currents decrease with increasing scan Cited by: Platinum(IV) chloride is the inorganic compound of platinum and chlorine with the empirical formula PtCl brown solid features platinum in the 4+ oxidation state.

Structure. Typical of Pt(IV), the metal centers adopt an octahedral coordination geometry, {PtCl 6}.This geometry is achieved by forming a polymer wherein half of the chloride ligands bridge between the platinum centers.

The Platinum Rule by Dr. Tony Alessandra: We have all heard of the Golden Rule-and many people aspire to live by it. The Golden Rule is not a panacea. Think about it: "Do unto others as you would have them do unto you." The Golden Rule implies the basic assumption that other people would like to be treated the way that you would like to be.

Platinum is the most valued precious metal; its value exceeds even that of has a beautiful silver-white color, and, unlike Silver, does not is unaffected by common household chemicals and will not get damaged or discolored by chlorine, bleach, or detergents. 4 TABLE OF CONTENTS, continued NITRATE, High Range, Test ‘N Tube, Chromotropic Acid Method.

Funnel G. K-Cup ® Portion Pack Holder. Platinum. Platinum in alchemy is represented by a symbol which is actually the combination of two different alchemical symbols, namely silver (Moon) and gold (Sun).

Alchemists thought that platinum was the mixture of gold and silver and that is why the symbol was created this way. Lead. Next in our list of alchemical symbols is lead. Being one. The reaction of Pt metal particles on SiO 2 (Aerosil) and γ-Al 2 O 3 supports with Cl 2 (–% by vol.) in N 2 or He in a flow system at temperatures (T r) in the range – K has been studied with XRD, TEM, uv-diffuse reflectance spectroscopy, and temperature-programmed reduction (TPR) of the SiO 2, for 5–25% Cl 2 only PtCl 2 results, forming large (up to nm diam.

The carbochlorination behavior of scrapped honeycomb-type automobile catalysts was investigated using a chlorine and carbon monoxide gas mixture to fully extract platinum and rhodium in the catalysts. The recoveries of platinum, rhodium, and base metals are monitored by ICP-AES analyses.

William Willis jun. () had been been looking for ways to make photographs with the most suitable metal he cold think of. Inthe British Journal of Photography announced his Platinum Printing process. Platinum(II) chloride is the chemical compound Pt Cl 2. It is an important precursor used in the preparation of other platinum compounds.

It exists in two crystalline forms, but the main properties are somewhat similar: dark brown, insoluble in water, diamagnetic, and odorless. It's like last time or to convert this into moles of platinum by dividing by its atomic mass.

Platinum group, six metals, in order of increasing atomic weight, ruthenium (Ru), rhodium (Rh), palladium (Pd), osmium (Os), iridium (Ir), and platinum (Pt). The elements all possess a silvery white colour—except osmium, which is bluish white.
