5 mole copper (6.022 X 1023/1 mole Cu)
= 3 X 1024 atoms of copper
-----------------------------------
5 g of copper sulfate pentahydrate is equivalent to 0,02 moles.
copper sulphate gets hydrated in water and thus is diffusible.
Water vapors and sulfur dioxide are released.
weigh out 0.5 g of copper sulphate on a weighing balance. u can use weighing paper to weigh the substance.
Copper sulfate itself is white/colorless when anhydrous. However, it's hygroscopic and the pentahydrate (the usual form) is blue... in fact, it's just about the same color as the sidebar over to the left there.
aqueous copper sulphate having high conductive hydroxide ions were as no in solid Copper sulphate.
Hydrated Copper Sulphate is CuSO4.5H2O and Anhydrous copper sulphate is just CuSO4. Therefore, hydrated copper sulphate has extra mass due to water molecules present in it.
copper sulphate gets hydrated in water and thus is diffusible.
Anhydrous or hydrated copper sulphate crystals? And from what?
CuSO4
it is bright pink!
On heating hydrated Copper Sulphate (CuSO4 . 5 H2O), the result is the removal of water molecules of crystallization, which for this very compound is 5 molecules per molecule of copper sulphate. The process cited above is termed as dehydration.
1. Increase the temperature of the water. 2. Use copper sulphate in the finely powered form instead of copper sulphate crystals (if hydrated). 3. Stir.
CuSO4 . 2H2O
Blue, because the copper cations become hydrated and the hydrated ions have a blue color.
Pouring water on it because when it is heated it turns to an endothermic reaction and the hydrated part is boiled put of the compound it is then Anhydrous copper sulphate. When you add water it is hydrated again and this is an exothermic reaction. Which can get extremely hot so don't pour it on your hand and then hydrate it.
Water vapors and sulfur dioxide are released.
You would get water in the gas phase (steam). The word "hydrated" means that there are water molecules mixed in with the copper sulphate, and so when you heat it, you will turn that water into steam, freeing it. Because of the high melting point of ionic compounds like copper sulphate, it will not be affected by heating unless you go to extemely high temperatures.
