Copper sulfate crystals are washed with alcohol to remove any impurities or excess water that may be present on the surface of the crystals. Alcohol can help to dissolve these impurities and evaporate quickly, leaving behind clean and pure copper sulfate crystals.
You have this backwards. Copper sulfate, CuSO4.5H2O is blue. When it is gently heated, it loses water and turns white.CuSO4.5H2O --> CuSO4 + 5 H2O.The white substance is anhydrous copper sulfate. If you put water on it it turns blue again.
When sulfuric acid reacts with black copper oxide and is heated gently, the copper oxide is reduced to copper and water is formed. The reaction can be represented as follows: CuO (s) + H2SO4 (aq) → Cu (s) + H2O (l) + SO2 (g)
You can try soaking the affected area with warm water to help dissolve the borax crystals. Once the crystals have softened, gently scrub the area with a soft brush or cloth. Repeat the process as needed until the crystals are fully dissolved.
You can get salt crystals out of salt water by evaporating the water. This can be done by leaving the salt water in a shallow container in the sun or by heating it gently. As the water evaporates, salt crystals will start to form and can be collected.
To effectively remove corrosion from copper, you can use a mixture of vinegar and salt or a commercial copper cleaner. Apply the solution to the corroded areas and scrub gently with a soft brush or cloth. Rinse the copper thoroughly with water and dry it completely to prevent further corrosion.

aluminum oxideMicrodermabrasion procedure involves the spraying of very fine microdermabrasion crystals onto the surface of the skin so as to gently exfoliate and peel away the old and dead skin cells. Usually, aluminum oxide crystals(chemical formula Al2O3) is recommended due to its non-toxicity properties and does not provoke any side effects or surface skin irritations.

By using a spatula and stire it gently by using a stirring rod.
To effectively clean copper using vinegar and salt, create a mixture of equal parts vinegar and salt. Apply the mixture to the copper surface and gently scrub with a soft cloth or sponge. Rinse the copper with water and dry thoroughly. This method helps to remove tarnish and restore the shine of the copper.
Yes, though it is helpful if you heat it in the microwave to remove the crystals. Crystals occur when it "sugars out". +++ The honey has not changed chemically or "gone off", just partially separated. Stir it well after melting it. You can also heat it by using a pan of water as a bain-marie - heat very gently, stir well.
1. Place 25cm3 of dilute sulphuric acid in a beaker. 2. Ass small amounts of solid copper oxide powder to the acid. Keep adding powder until some copper oxide that hasn't reacted is left on the bottom. 3. Filter the solution to remove the copper oxide that hasn't reacted. 4. Transfer the filtrate into a evaporating basin. 5. Heat the contents of the evaporating basin gently. 6. When about a third of the water has evaporated, leave the solution to cool. 7. Examine the crystals which have formed.
