What happens when ferrous sulphate crystals in boiling tube when heated by spirit lamp?
When ferrous sulfate crystals are heated in a boiling tube with a spirit lamp, they undergo thermal decomposition. The crystals lose water of crystallization and change color from green to white as they form anhydrous ferrous sulfate. This reaction releases water vapor and sulfur dioxide gas.
How do you obtain copper sulfate crystals from a mixture of copper sulfate and sand?
To obtain copper sulfate crystals from a mixture with sand, you can dissolve the mixture in water. The copper sulfate will dissolve, while the sand will not. You can then filter the solution to separate the sand from the copper sulfate solution. By evaporating the water from the copper sulfate solution, you can obtain copper sulfate crystals.
Can copper sulphate crystals dissolve in water?
Yes, copper sulfate crystals can dissolve in water. When added to water, the crystals break down into copper ions and sulfate ions, forming a solution of copper sulfate.
Which dissolve first the coarse copper sulfate crystals or the powdered copper sulfate?
The powdered copper sulfate will dissolve faster than the coarse copper sulfate crystals because the increased surface area of the tiny particles allows for quicker contact with the solvent, facilitating a faster dissolution process.
Is copper sulfate crystals a mixture or an element?
Neither, coper sulfate is not a mixture and it is not an element. Coper Sulfate is a chemical compound.
