Which pollutants can be removed from the chimney gases of factories and power stations by treatment with calcium carbonate?
Calcium carbonate can help remove sulfur dioxide and acidic gases like nitric oxide from chimney gases by neutralizing them to form less harmful substances like calcium sulfate and calcium nitrate. This process is known as flue gas desulfurization and can help reduce air pollution emissions from industrial sources.
Substance that will remove sulfur dioxide?
Basically, sulfur dioxide is a acidic gas. As acid reacts with alkali, carbonates and metals, all 3 are actually ideal to remove sulfur dioxide. However, in the context of removing sulfur dioxide due to air pollution, reacting sulfur dioxide with alkali and carbonate would be more appropriate. For example, removing sulfur dioxide with calcium carbonate would result in calcium sulfate, water and carbon dioxide.
Why is it harder to remove an electron from Magnesium than it is to remove an electron from Calcium?
Zinc has more electrons in its outer energy level than Calcium. Because of this, itsnucleus is more attracted to this energy level and pulls it more the nucleus in Calcium. Because of this greater attraction it is harder to remove the electron from Zinc.
How do you remove calcium carbonate from limestone floors?
You can remove calcium carbonate from limestone floors by using a mild acid solution, such as vinegar or lemon juice, to dissolve the mineral deposits. Apply the solution to the affected areas, allow it to sit for a few minutes, then scrub the surface with a brush or scrubbing pad. Rinse the area thoroughly with water to remove any remaining residue.
How does calcium hydroxide remove sulfur dioxide?
Calcium hydroxide reacts with sulfur dioxide to form calcium sulfite. The reaction helps to remove sulfur dioxide from a gas stream by capturing it in the form of a less harmful compound. This process is commonly used in industries to reduce sulfur dioxide emissions.
How and why calcium carbonate is used to remove the acidic gases produced from coal- fired power stations?
Calcium carbonate easily react with acids and a neutralizing reaction occur.
Which chemical could be used to remove the acidic sulphur dioxide from flue gases?
Lime (calcium oxide or calcium hydroxide) is commonly used to remove acidic sulfur dioxide from flue gases. The sulfur dioxide reacts with lime to form calcium sulfite or calcium sulfate, which can then be removed from the gas stream.
What dissolves calcium and how can it be effectively removed from surfaces?
Calcium can be dissolved by acidic substances like vinegar or lemon juice. To effectively remove calcium from surfaces, you can use a mixture of water and vinegar or a commercial calcium remover. Scrubbing the surface with a brush or sponge can help to loosen and remove the dissolved calcium.

Why are waste gasses from coal-fired power stations passed through calcium carbonate?
Waste gases from coal-fired power stations are passed through calcium carbonate to remove sulfur dioxide from the gas stream through a process known as flue gas desulfurization. In this process, the calcium carbonate reacts with the sulfur dioxide to form calcium sulfate, a solid compound that can be easily removed, reducing air pollution and environmental impacts.
How is vinegar able to remove an egg's calcium shell?
Vinegar is an acid that reacts with the calcium carbonate in the eggshell, breaking it down into calcium ions and carbon dioxide gas. This reaction dissolves the eggshell, leaving the membrane intact.
How is calcium carbonate used in coal fired power stations?
Calcium carbonate is commonly used as a sorbent to remove sulfur dioxide (SO2) emissions from flue gas in coal-fired power stations. When calcium carbonate reacts with SO2, it forms calcium sulfate, which can be captured and disposed of. This process helps to reduce air pollution and comply with environmental regulations.
What is the nature of the aqueous solution of slaked lime?
The aqueous solution of slaked lime, or calcium hydroxide, is basic in nature. It can react with acidic substances to form salts and water. Slaked lime is often used to neutralize acidic soils or in water treatment to remove impurities.
How do you remove calcium deposits?
Calcium can be broken down with an acidic solution of some kind. There are cleaning agents sold which are made specifically for this. You can remove calcium deposits using baking soda and white vinegar, depending on what kind of surface you are cleaning, you can scrub the area with either steel wool or a nylon scrubber. This is a lot less expensive than store bought products. You can also use salt and vinegar.
Do skimmers remove calcium?
No
How does calcium carbonate reduce harmful emissions from coal-fired power stations?
Coal contains sulphur and when this is burnt(heated) sulphur dioxide is produced, this is a greenhouse gas. To remove this greenhouse gas, this gas is passed a mechanism like a shower that is able to dissolve it and make it an acid. Then this acid sulphur is neutralized with calcium carbonate to form calcium sulphate, water and carbon dioxided
