What do sulfuric acid and calcium carbonate make?
Sulfuric acid and calcium carbonate react to form calcium sulfate, carbon dioxide gas, and water. This is a chemical reaction where the acid reacts with the carbonate to form a salt, releasing carbon dioxide in the process.
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.
What happens to copper sulfate particles when they dissolve?
When copper sulfate particles dissolve in water, they dissociate into copper ions (Cu2+) and sulfate ions (SO4²-) due to the polar nature of water molecules. These ions become surrounded by water molecules in a process called hydration, effectively spreading out and becoming dispersed in the solution. This results in a homogeneous solution with the copper sulfate particles no longer present as solid entities but rather as individual ions within the liquid.
How has industry overcome the release of harmful sulfur dioxide through smelting?
The sulfur dioxide can be captured in a solution to form ammonium sulfate, a fertilizer. A method using electrons bombardment is known for this process.
How do sulfate precipitates form in aqueous solutions?
Sulfate precipitates form in aqueous solutions when sulfate ions combine with metal ions to create insoluble compounds, which then separate from the solution as solid particles. This process is known as precipitation and occurs when the solubility limit of the compound is exceeded.
What minerals are in a car battery anode?
Common minerals found in a car battery anode include lead dioxide and lead sulfate. Lead dioxide is typically used in the positive plate of the anode, while lead sulfate forms on the negative plate during the discharge process.
What is the chemical formula for distilled water magnesium sulfate and carbon dioxide?
What is the chemical formula of distilled water, magnesium sulfate and C02
What are the means of biogas purification?
Removal of unwanted particles and gasses. Sulfur dioxide is one of the unwanted constituents of biogas. This is often removed by allowing the biogas to infiltrate a bed of iron filings. There the sulfur dioxide combines with the iron to make iron sulfate.
What kind of change is grinding copper sulfate pentahydrate?
Grinding copper sulfate pentahydrate is a physical change because no new substances are formed during the process. The copper sulfate remains the same chemical compound, but its physical state is altered as it is broken down into smaller particles.
Why is heating copper sulfate a chemical change?
Heating copper sulfate causes a chemical change because it leads to the compound decomposing into different substances, namely copper oxide and sulfur dioxide. This change alters the chemical composition and properties of the original compound, indicating a chemical reaction has occurred.
What is the process called which is used in separation of mixture of sand and copper sulphate?
The process used to separate a mixture of sand and copper sulfate is called filtration. The mixture is poured through a filter paper, allowing the sand particles to be trapped while the copper sulfate solution passes through as the filtrate.
Is carbon- dioxide present in copper sulphate?
No, carbon dioxide is not present in copper sulfate. Copper sulfate is composed of copper, sulfur, and oxygen atoms, not carbon dioxide. Carbon dioxide is a molecule composed of carbon and oxygen atoms.
