Cobalt (II) Chloride
The ionic compound CoCl2 is called cobalt(II) chloride.
The common name for COCl2 is phosgene. It is a toxic gas that was used as a chemical weapon during World War I.
Iupac name of COCl2
The gram equivalent weight of CoCl2 is calculated by dividing the molar mass of CoCl2 by its valency. The formula weight of CoCl2 is 129.84 g/mol. Since the valency of CoCl2 is 2, the gram equivalent weight would be 129.84/2 = 64.92 g/equiv.
Yes, CoCl2 * 6H2O is the hexahydrate of the an hydrate CoCl2.
Blue, and Pink. Its a chemistry experiment.When hydrated the cobalt cloride is pink. When it dries it's blue.
To answer this question you need the molecular weight of CoCl2. CoCl2 molecular weight is 129.84 g/mole 230g CoCl2 divided by the molecular weight 230 g / 129.84 g/mole = 1.77 moles of CoCl2 Multiply the moles by Avagodro's number 1.77 mole * 6.022 X 1023 molecules/mole = 1.07 X 1024 molecules of CoCl2
CoCl2 forms ionic bonds due to the large electronegativity difference between cobalt and chlorine. In CoCl2, cobalt loses two electrons to chlorine atoms, resulting in the formation of Co2+ cations and Cl- anions, which are held together by electrostatic forces.
CoCl2
Phosgene is a compound of carbon, oxygen, and chlorine. Its formula is COCl2. The lower case O in this formula shows that this is cobalt. The lower case I showes that we are talking about some unknown element.
When CoCl2·6H2O is heated, the water molecules are driven off, leaving anhydrous CoCl2. This is a physical change, not a chemical reaction. However, the anhydrous CoCl2 can undergo chemical reactions depending on the conditions and other reactants present.
To determine the mass of CoCl2 6H2O to prepare a 0.30M solution in 50.0ml, we first calculate the molar mass of CoCl2 6H2O. The molar mass is 237.93 g/mol, so for a 0.30M solution in 50.0ml, we can use the formula: mass = molarity x volume (L) x molar mass. Therefore, the mass of CoCl2 6H2O needed is 3.57 grams.
