Limestone is an alkali and will therefore react with the acid in the lake, thereby reducing the acidity.

Why is it safer to use powdered limestone instead of calcium hydroxide to neutralise acidic soil?

Powdered limestone is safer because it releases calcium and carbonate ions slowly, preventing a sudden increase in pH which can harm plants. Calcium hydroxide, on the other hand, can raise the pH too quickly, leading to potential toxicity in the soil. Additionally, powdered limestone is less likely to cause chemical burns or skin irritation compared to calcium hydroxide.


Is cement a mixture of limestone and silicon dioxide?

Cement is a powdered substance made primarily from limestone, clay, and other minerals like iron ore and gypsum. It is not a direct mixture of limestone and silicon dioxide. The limestone and clay are heated together to form a compound called clinker, which is then ground into a fine powder to make cement.


What gas is given off when powdered iron metal is added to hydrochloric acid?

When powdered iron metal is added to hydrochloric acid, hydrogen gas is given off as a product. This reaction also forms iron(II) chloride as a result.


Why is limestone added to the blast furnace during the extraction of iron?

Limestone is added to the blast furnace during the extraction of iron to act as a flux. It helps to remove impurities, such as silica, from the iron ore by combining with them to form slag. The slag can then be easily separated from the molten iron.


Why does limestone bubbles when acid is added to its surface?

Limestone contains calcium carbonate, which reacts with acid (such as hydrochloric acid) to form carbon dioxide gas. The release of carbon dioxide gas creates bubbles or fizzing on the limestone surface.

Why is powdered limestone sometimes deliberately added to lakes in countries like Norway and Sweden?

Powdered limestone is added to lakes in Norway and Sweden as a restoration technique to combat acidification caused by acid rain. Limestone acts as a buffer, neutralizing the acidity in the water and improving the pH levels to support aquatic life. This helps to restore the ecological balance of the lake and promote biodiversity.

Can Limestone be used for the smell of a decompostion of a dead animal?

Lime (quicklime) is made from limestone- but it is not the same thing. Agricultural lime is powdered limestone. Quicklime is limestone (calcium carbonate) that has been roasted and changed to Calcium Oxide. Slaked quicklime is quicklime that has had water added- Calcium hydroxide. Quicklime is used for odor control.

What do you get when powdered quartz and powdered limestone are soda are mixed?

When powdered quartz, powdered limestone, and soda (sodium carbonate) are mixed together, it forms a type of glass known as soda-lime-silica glass. This type of glass is commonly used in windows, bottles, and containers due to its durability and transparency.


Why do the neutralising effects of powdered limestone on soil last longer than that of slaked lime?

no


How can you turn limestone to cement?

Powdered limestone has to be heated with powdered clay to turn it into to cement. You can then use cement and powder it, then mix with water, sand crushed rock and a slow reaction takes place forming concrete. It is in the Cors Science GCSE
