What is chloroplatinate?
A salt of chloroplatinic acid, H2PtCl6.
What can dissolve platinum?
Aqua Regia (HCL+Nitirc acid) Pt+4HNO3+6HCl=H2PtCl6+4NO2+4H2O heat is necessary
How many moles of precatalyst H2ptcl6 are used in this reaction?
The number of moles of catalyst depends on the reaction under consideration. Compared to the substrate, about 10-2 to 10-6 times of the catalyst can be used. The lower the amount of the catalyst, the more effective it is.
What is a chemical property of platinum?
The most common oxidation states of platinum are +2 and +4. The +1 and +3 oxidation states are less common, and are often stabilized by metal bonding in bimetallic (or polymetallic) species. As is expected, tetracoordinate platinum compounds tend to adopt 16-electron square planar geometries. While elemental platinum is generally unreactive, it dissolves in aqua regia to give soluble hexachloroplatinic acid ("H2PtCl6", formally (H3O)2PtCl6·nH2O ) Pt + 4 HNO3 + 6 HCl → H2PtCl6 + 4 NO2 + 4 H2O As a soft acid, platinum has a great affinity for sulfur, such as on dimethyl sulfoxide (DMSO); numerous DMSO complexes have been reported and care should be taken in the choice of reaction solvent. source: Wikipedia
Is platinum weak or strong?
Well here are some notes about platinum : As a pure metal, platinum is silvery-white in appearance, lustrous, ductile, and malleable.[3] It does not oxidize at any temperature, although it is corroded by halogens, cyanides, sulfur, and caustic alkalis. Platinum is insoluble in hydrochloric and nitric acid, but dissolves in aqua regia to form chloroplatinic acid, H2PtCl6.[4] I WOULD SAY THAT YES! the andswer would be that platinum is strong well can bee (:
When platinum is heated what happened?
When platinum is heated, it undergoes a physical change rather than a chemical change. Initially, platinum will expand due to thermal expansion, and it may change color temporarily due to the formation of a thin oxide layer on its surface. However, platinum will not undergo any significant chemical reactions at typical heating temperatures.
