Is Phosgene organic or inorganic?

Phosgene is an organic compound. It is a colorless gas with the formula COCl2.


What is the charge on the cobalt ion in CoCl2?

The charge on the cobalt ion in CoCl2 is +2. This is because each chloride ion has a charge of -1, and there are two chloride ions present in CoCl2, making the overall charge of the compound neutral.


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 is the ionic compounds of CoCl2?

This compound is cobalt(II) chloride.


What is the oxidation number of Carbon in COCl2?

The oxidation number of carbon in COCl2 is +2. In this compound, oxygen has an oxidation number of -2, and chlorine has an oxidation number of +1. Since the overall charge of COCl2 is zero, the oxidation number of carbon must be +2 to balance out the charges.


Whatcolor is change by heat CoCl2-6H2O?

The color of hydrated cobalt chloride (CoCl2•6H2O) changes from blue to pink when heated due to the dehydration of the compound. Upon heating, the water molecules are removed, leaving behind anhydrous cobalt chloride which is pink in color.


What is the covalent compound formula cobalt chloride?

The formula for cobalt chloride, a covalent compound, is CoCl2. In this compound, cobalt has a charge of +2 and chloride has a charge of -1, so two chloride ions are needed to balance the charge of one cobalt ion.


Could you tell me the Gram equivalent weight 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.


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.
