What else can I help you with?
Why does one of the reactant copper carbonate is added in excess when preparing a sample of copper sulphate crystals?
Excess copper carbonate is added to ensure that all the copper sulphate is fully converted. This helps to make sure that all the starting material is used up and that the reaction goes to completion, resulting in a higher yield of pure copper sulphate crystals.
What is the effect of excess of sulphate ions in drinking water?
Excess of sulphate ions in drinking water can give it a bitter taste and cause gastrointestinal issues like diarrhea in some people. High levels of sulphate can also have a laxative effect and may impact the taste and quality of the water.
What are the uses of sulphate?
used as a herbicide, fungicide and pesticide. Also to test blood for anaemia and usually at schools used to make crystals

Can copper sulphate crystals be used for jewelry?
Copper sulfate crystals are not typically used for jewelry as they are primarily used in agricultural, analytical, and industrial applications rather than in jewelry making. Additionally, exposure to copper sulfate can cause skin irritation. If you are looking for crystals for jewelry, you might consider gemstones or crystals that are designated safe for such purposes.
How is calcium sulphate useful?
Calcium Sulphate, CaSO4 is also known as Gypsum or Alabaster. It is used for making plaster of Paris, dried gypsum and as a filler or glaze in paper making. Medically, it is used to make splints and casts for fractures.
Which methods is used to obtain pure copper sulphate from impure sample and how?
One method to obtain pure copper sulfate from an impure sample is by recrystallization. In this process, the impure sample is dissolved in water, and then the solution is heated and slowly cooled to allow pure copper sulfate crystals to form. These crystals are then filtered out and dried to obtain the pure compound.
Why is barium chloride and alcohol used in the limit test for sulphates?
Barium chloride is used in the limit test for sulphates because it forms a precipitate with sulphate ions. Alcohol is added to the mixture to promote the formation of small crystals, which makes it easier to detect the presence of sulphate ions in the sample.
What mineral was used in the manufacture of drywall?
Calcium sulphate dihydrate IS (not was ) used for making drywall, sheetrock, wallboard, etc.
How can aluminium sulphate be used to benefit plants?
Aluminium sulphate can be used to lower the pH of soil, making it more acidic and improving the availability of nutrients like phosphorus for plants. This can help plants grow better and healthier.
What is The name of the copper sulphate after being heated?
Copper Sulphate usually is found in a hydrated form (i.e., water molecules are incorporated into the crystals.) Pure copper sulphate is a pale, greenish gray color. The familiar blue color only occurs in hydrates of copper sulphate (i.e., in crystals that incorporate H20 molecules). Heating the blue crystals can drive off the water. It's still called copper sulphate after you do that. For substances like copper sulphate that naturally attract water, the adjective, anhydrous often is used to describe the pure (water free) state. If you heat copper sulphate to a temperature of 650C, it will decompose into something else. http://en.wikipedia.org/wiki/Copper_sulphate
