Question

Write the balanced equation for the hydration of CuSO4. Indicate the physical states using the abbreviations (s), (l), or (g) for solid, liquid, or gas, respectively. Use (aq) to indicate the aqueous phase. Indicate appropriate charges on negative and positive ions if they are formed.

Answer 1

Answer:

CuSO4(s) + 5 H2O(l) → CuSO4*5H2O(s)

Explanation:

We start with the anhydrous copper(II) sulfate (CuSO4).

For the hydration of CuSO4, we add water (H2O).

CuSO4(s) + H2O(l)

The hydrated form of CuSO4 is written as CuSO4* xH2O. This hydrated form here will still be solid = crystals.

The most common form of CuSO4 crystals is pentahydrate.

CuSO4*5H2O

CuSO4(s) + 5 H2O(l) → CuSO4*5H2O(s)
