Introduction
Copper sulphate, also known as cupric sulphate or blue vitriol, is a versatile chemical compound with a wide range of applications in both industrial and domestic settings. With a purity of 93%, copper sulphate is particularly effective for various household tasks, including gardening, cleaning, and pest control. This guide explores the numerous domestic uses of copper sulphate 93%, providing practical examples and safety considerations for individuals in the UK.
What is Copper Sulphate 93%?
Copper sulphate (CuSO₄) is an inorganic compound composed of copper, sulfur, and oxygen. At 93% purity, it typically exists as blue crystals and is highly soluble in water, making it suitable for various applications. It is commonly used as a fungicide, algaecide, root killer, and herbicide in both agricultural and non-agricultural settings.
Domestic Applications of Copper Sulphate 93%
1. Moss and Algae Removal from Roofs and Patios
Copper sulphate is effective in eliminating moss and algae from outdoor surfaces. To prepare a 5% solution, dissolve 50 grams of copper sulphate crystals in 1 litre of water. For larger areas, mix 500 grams with 10 litres of water. Apply the solution using a garden sprayer on a dry day, ensuring even coverage. The moss will begin to die off within a few days, after which it can be brushed away.
2. Garden Fungicide
Copper sulphate serves as a fungicide to protect plants from fungal infections. A common preparation is the Bordeaux mixture, which combines copper sulphate with hydrated lime and water. A typical ratio is 1:1:100 (1 kg copper sulphate, 1 kg hydrated lime, and 100 litres of water). Spray the mixture onto plants to prevent diseases like downy mildew and blight.
3. Swimming Pool Algaecide
To control algae growth in swimming pools, copper sulphate can be used as an algaecide. The recommended dosage is approximately 0.2 mg/L of copper ion concentration in the pool water. Care must be taken to avoid overuse, as excessive copper can stain pool surfaces and harm swimmers.
4. Root Killer for Drains
Copper sulphate can be used to eliminate tree roots invading sewer lines. Pouring 100 grams of copper sulphate crystals into the toilet and flushing can help kill roots in the pipes. Repeat the process every six months to maintain clear pipes. Ensure that the local regulations permit this use, as copper compounds can be harmful to the environment.
5. Wood Preservative
Copper sulphate acts as a wood preservative, protecting against rot and insect damage. A solution can be made by dissolving 100 grams of copper sulphate in 1 litre of water. Apply the solution to wood surfaces using a brush or sprayer, allowing it to dry thoroughly. This treatment is especially useful for outdoor wooden structures like fences and decks.
6. Etching and Crafting
In arts and crafts, copper sulphate is used for etching designs onto metal surfaces. By applying a solution of copper sulphate to metals like zinc or aluminum, artists can create intricate patterns. Proper safety measures, including gloves and eye protection, should be used during this process.
7. Aquarium Parasite Treatment
Copper sulphate is utilized in aquariums to treat parasitic infections in fish. The concentration must be carefully controlled, typically around 0.15 to 0.2 mg/L, as higher levels can be toxic to aquatic life. It's essential to remove invertebrates and adjust the dosage based on water hardness.
8. Homemade Crystal Decorations
For educational or decorative purposes, copper sulphate can be used to grow blue crystals. Dissolve copper sulphate in hot water until saturation, then suspend a string or porous material in the solution. Over time, crystals will form on the material, creating visually appealing decorations. This activity should be supervised, especially with children, due to the chemical's toxicity.
Safety Precautions
-
Protective Gear: Always wear gloves, safety goggles, and protective clothing when handling copper sulphate.
-
Storage: Keep the chemical in a secure, labeled container away from children and pets.
-
Environmental Impact: Avoid disposing of copper sulphate in drains or natural water bodies, as it can be harmful to aquatic life.
-
First Aid: In case of skin contact, wash the area thoroughly with water. If ingested, seek immediate medical attention.
