## Question:

Determine the number of grams of water in 7.00 g of copper(II) sulfate pentahydrate.

## Copper (II) Sulfate Pentahydrate

{eq}{/eq}

It is a blue crystalline solid and is soluble in water, while the anhydrous salt is white in color. Copper sulfate can be prepared by reaction of copper and its oxides by sulfuric acid.

{eq}\displaystyle{ 1. \ CuO + H_2 SO_4 \longrightarrow CuSO_4 + H_2O \\ 2. \ Cu(OH)_2 + H_2 SO_4 \longrightarrow CuSO_4 + H_2 O \\ 3. \ Cu + H_2 SO_4 + \frac{1}{2} O_2 \longrightarrow CuSO_4 + H_2O \\ } {/eq}

Copper sulfate is a very important industrial compound as it can be used for

1. Electroplating and electrotyping.

2. As a mordant in dyeing.

3. In electric batteries.
