Is cupric sulfate blue?

Most people think that Cupric sulfate or Copper(II) sulfate, is blue in colour. But actually it is not. Blue colour in Copper(II) sulfate is due to the presence of Water molecules in it. This form is called Copper(II) sulfate Pentahydrate[CuSO4.5H2O], which most people see. If it does not have any water molecules in it, the thing is in pure state and is White in colour. This form is Anhydrous Copper(II) sulfate[CuSO4]. This form is rarely seen, because it can absorb water itself from the nature and become blue in colour. So from this we know that very pure Copper(II) sulfate is not blue, But its Pentahydrate form is blue.


How does mining copper affect the hydrosphere?

Mining copper can lead to water pollution in the hydrosphere through the release of acidic mine drainage containing heavy metals like copper. This can harm aquatic life and affect water quality in rivers and streams. Mines also require significant water usage, leading to depletion of local water sources in some cases.
