Yes, white CuSO4 can absorb 1 to 5 molecules of H2O (mono- and penta-hydrates (blue) are formed).
Hygroscopic substances are used to absorb humidity.
Potassium hydroxide is hygroscopic and deliquescent.
CuSO4 · 5H2O has 5 water molecules attached to each CuSO4 molecule.
The ratio of moles of CuSO4 to moles of water in CuSO4•5H2O is 1:5. This is because there is one mole of CuSO4 for every five moles of water in the compound.
CuSO4 is the chemical formula of copper(II) sulfate.
Non-Hygroscopic
The hair of the tail of horse is hygroscopic material.
Polyol Ester is also hygroscopic
CuSO4 is copper (II) sulfate. The balanced equation for CuSO4 with water is CuSO4 + H2O reacts to become Cu+2 + HSO4-2 + OH-.
Yes. They do not contain the same proportion of CuSO4, however. The moles of CuSO4 . 5 H2O are more massive.
Hygroscopic substances are used to absorb humidity.
Yes, CuSO4 is an electrolyte.
Potassium hydroxide is hygroscopic and deliquescent.
No, the percent by mass of copper in CuSO4 5H2O will be different than in CuSO4 because CuSO4 5H2O includes water molecules in addition to the copper sulfate compound itself. Therefore, the total mass of CuSO4 5H2O will be greater, resulting in a lower percent by mass of copper in CuSO4 5H2O compared to CuSO4.
their isn't one CuSO4 is an anhydrous salt which will absorb water so the way to find out how much is in it is to find out the difference in water befor and after addition and calculate it by finding the mols of water absorbed incomplarison with the number of mols of CuSO4 used. it is normally wrighten nH2O. CuSO4
As far as I know, the PVC is not hygroscopic, it doesn't absorb the moisture. There are several types of PVC though, so there could be some hygroscopic PVC resin, but I haven't encountered it yet. Normally it is dried by hot air driers, which are not suitable for hygroscopic materials, therefore I assume PVC is not hygroscopic...
The chemical equation for the reaction between hydrochloric acid (HCl) and copper (II) sulfate (CuSO4) is: 2 HCl + CuSO4 -> CuCl2 + H2SO4
