CoCl2.6H2O has 6 water molecules attached as secondary valencies and 2 chlorine atoms are serving as the primary valencies. The secondary valencies are directional in nature and hence they lead to the geometry of it.

The geometry of this compound is Octahedral with cobalt showing a coordination no. of 6.

How do you dehydrate CoCl2 6H20?

To dehydrate cobalt(II) chloride hexahydrate (CoCl2·6H2O), you can gently heat the compound in a dry oven or on a hot plate at a temperature around 100-120°C. This process drives off the water molecules, resulting in anhydrous CoCl2. It's important to monitor the temperature to avoid overheating, which can lead to decomposition. Always handle with care, as cobalt compounds can be hazardous.


How many Co atoms are there in 230 grams of CoCl2?

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


What weight of solid CoCl2 would be need to prepare 500ML of 0.150M CoCl2 solution?

To calculate the weight of solid CoCl2 needed, you can use the formula: weight = (molarity) x (volume) x (molar mass) Substitute the values: weight = 0.150 mol/L x 0.5 L x 129.84 g/mol = 9.74 g of CoCl2 is needed.


Why is CoCl2 in Hygrometers?

CoCl2, or cobalt chloride, is used in hygrometers as a humidity indicator because it changes color when exposed to different levels of humidity. In its anhydrous form, CoCl2 is blue, but it turns pink when it absorbs moisture from the air. This color change makes it easy to visually determine the humidity level.


What is the balanced molecular equaton for FeCl3 plus CoCl2?

The balanced molecular equation for FeCl3 + CoCl2 is: 2FeCl3 + 3CoCl2 → 2FeCl2 + 3CoCl3

How many grams of CoCl2 6H2O are needed to prepare 50.0ml of a 0.30M CoCl2 solution?

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.


How many grams of CoCl2 6H2O must you measure out in a container to have exactly Avogadros number of particles?

To have Avogadro's number of particles of CoCl2 6H2O, you would need to measure out 1 mole of the compound. This is equivalent to the molar mass of CoCl2 6H2O in grams, which is approximately 237.93 grams.


What color is CoCl2-6H2O-ethanol?

The color of CoCl2-6H2O in ethanol solution is typically pink or rose-red. This color arises from the presence of the hydrated cobalt(II) ions in the complex.


Would CoCl2 6H2O cause a chemical reaction?

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.

When a sample of 20.0 g of CoCl2 - 6H2O is dried in an oven until dry CoCl2 is obtained what is the mass of dry cobalt chloride?

Equation:CoCl2.6H2O + heat --> CoCl2 + 6H2OYou have the mass of CoCl2.6H2O, which is 20g.You know the Mr of CoCl2.6H2O as well:58.93 + 35.5(2) + 6(18)= 237.93gmol-1 (The 18= H2O)You know the formula to calculate the no. of moles:n=mass/Mr, therefore n= 20/237.933 = 0.0841 molesThe ratio of CoCl2.6H2O: CoCl2 is 1:1, therefore CoCl2 has the same number of moles as does CoCl2.6H2O.So you want the mass of CoCl2? Well you havethe the Mr of it and now you have the no. of moles.Mr of CoCl2:58.93 + 35.5(2)= 129.93 (Or you could simply do 237.93 - 6(18) )Since n=mass/Mr you simply rearrange to get mass by itself. Which is:mass= n x MrTherefore the mass ofCoCl2ismass = 0.0841 x 129.93 = 10.92g (Answer)Daniel Hajsadr


What is the hybridization of the central atom of COCl2?

The central atom in COCl2 is carbon. The carbon atom is sp2 hybridized in COCl2, meaning it has three electron pairs in sp2 hybrid orbitals and forms sigma bonds with three surrounding atoms in a trigonal planar geometry.
