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.
Describe the experimental procedure for determining the formula for a hydrate?
To determine the formula for a hydrate, the hydrate is heated to remove the water of hydration, leaving behind the anhydrous compound. The mass of water lost and the mass of the anhydrous compound are measured. By comparing these masses, the ratio of water to anhydrous compound can be determined, leading to the formula of the hydrate.
What is the percentage of water in the hydrate CoCl2 and 6H2O Show your work?
To find the percentage of water in CoCl2·6H2O, calculate the molar mass of water (18.015 g/mol) and the molar mass of the whole compound. Molar mass of CoCl2·6H2O = 129.84 g/mol (CoCl2) + 6(18.015 g/mol) = 237.89 g/mol Now, compute the percentage of water: Percentage of water = (6 * 18.015 g/mol) / 237.89 g/mol * 100% ≈ 54.5% Therefore, the hydrate CoCl2·6H2O contains approximately 54.5% water.
What is the formula for cobalt trichloride?
There is more than one hydrate. If you are dealing with the dihydrate it is CoCl2 2H2O than it is blue (sorry but the keyboard won't let me put the 1st and last 2 as subscripts nor allow the dot between the two "2"s, similar to the dot used when you multiple 2x3=6 and don't want to use the letter x. This is what is used to make the test strips we give in labs. If you are dealing with the hexahydrate it is CoCl2 6H20 and this is seen as the pink colour of the test strip once exposed to water.
Does CoCl2 form one type of ion or more than one type of ion?
CoCl2 forms only one type of ion, which is the Co2+ ion. Each CoCl2 formula unit contains one cobalt ion with a 2+ charge, surrounded by two chloride ions.
When colbalt chloride unties with water to form hexahydrate its formula is written CoCL2 6H2O?
The correct formula for cobalt chloride hexahydrate is CoCl2·6H2O. The dot is used to differentiate between the compound and the water molecules in the crystal structure.
