| 7758-98-7 | 231-847-6 | 159.61 g/mol |
How do you find the mass of anhydrous copper sulfate?
Worked example
- The mass of hydrated copper sulfate = 127.95 g – 125.45 g = 2.50 g.
- The mass of water given off = 127.95 – 127.10 = 0.85 g.
- The percentage of water = 0.85 ÷ 2.50 x 100% = 34%
What mass of copper sulfate was in the hydrate?
11.3 g
The mass of the hydrate was 11.3 g.
What is copper sulfate anhydrous?
Copper(II) sulfate is a metal sulfate compound having copper(2+) as the metal ion. This forms as large, bright blue crystals containing five molecules of water (CuSO4∙5H2O) and is also known as blue vitriol. The anhydrous salt is created by heating the hydrate to 150 °C (300 °F).

What is the percent composition of anhydrous copper sulfate?
Anhydrous copper sulfate is 39.81 percent copper and 60.19 percent sulfate by mass, and in its blue, hydrous form, it is 25.47% copper, 38.47% sulfate (12.82% sulfur) and 36.06% water by mass.
How to find the mass of water of hydrated copper (II) sulfate?
In this experiment, a known mass of hydrated copper (II) sulfate is heated to remove the water of crystallisation. The mass of water is found by weighing before and after heating. This information is used to find x in the formula CuSO 4 .xH 2 O, using mole calculations
What is the difference between copper sulfate and copper hydrous?
Commercial copper sulfate is usually about 98% pure copper sulfate, and may contain traces of water. Anhydrous copper sulfate is 39.81 percent copper and 60.19 percent sulfate by mass, and in its blue, hydrous form, it is 25.47% copper, 38.47% sulfate (12.82% sulfur) and 36.06% water by mass.
