This image was build by X-ray imaging of salt. |
Now it is more complex than the crystal above for NaCl because we have a polyatomic ion in the crystal. The Yellow is the Sulfur attached to 4 oxygens (red). The brown color (i think its brown) is the copper. Notice regular repeating pattern. Its hard but if look inside the crystal there is one Cu per sulfate ion. |
![]() |
Notice the Dot between anhydrate and water. This dot means “WITH” and not to multiple. Thus there are exactly 5 water molecules for every 1 Cu+2 and 1 SO4-2 in the crystal. |
You will notice that water (it has 2 white hydrogen atoms) molecules are situated inside the crystals at particular regions in the crystal in exact ratios. This is a fixed ratio (stoichiometric ratio). It is hard but you can see the 5 water molecules per 1 copper ion and 1 sulfate ion. What makes it hard is that the crystal repeats in all directions. The water can be removed from the salt by heating it. |
