What is a Solution Hollows?
Solution hollows are small depressions or cavities formed in limestone or other soluble rock by the action of acidic water dissolving the rock over time. These hollows can form underground or on the surface. They are often found in areas with extensive limestone bedrock and are typically associated with karst topography.
Why does limestone turn into a powder when in vinagar?
When limestone, which is composed of calcium carbonate, reacts with vinegar (which contains acetic acid), a chemical reaction occurs that produces carbon dioxide gas. This gas bubbles through the solution and breaks the limestone down into calcium acetate, water, and carbon dioxide. The physical appearance of the limestone changes to a powdery form due to the breakdown of the solid structure as it dissolves.
How do you make k2cr2o4 solution?
It is prepared by roasting powdered chromite with potash and limestone, treating the cinder with a hot potassium sulfate solution and leaching.Alternatively, it may be prepared by the reaction of potassium dichromate and potassium hydroxide.
Is limestone a sedimentary rock made from shells of sea animals?
Yes, limestone is a sedimentary rock primarily made up of calcite and aragonite minerals, which are derived from the shells of marine organisms. Over time, these shells accumulate and are compacted to form limestone rock.
What is the common name for limestone?
The common name for limestone is simply "limestone".
Why is the limestone cave sometimes called the soultion cave?
Limestone caves are sometimes called solution caves because they are formed through a process called solution weathering. This occurs when water containing carbon dioxide dissolves the limestone rock, creating cave systems over time. The dissolved limestone is carried away in the form of a solution, hence the term "solution cave."
Is limestone a solution?
No it is not. Limestone itself is not a solution. Limestone is a rock which is primarily calcium carbonate as are marble and chalk. Calcium carbonate will react with water if the water contains dissolved Carbon Dioxide (forming a mild carbonic acid) resulting in Calcium Bicarbonate which is soluble and does form solution in water.

True or false Most caves and caverns originate by solution of limestone?
True.
What happens when a dilute solution of hydrochloric acid poured on a limestone rock?
It releases bubbles if carbon dioxide gas.
What has the author H K Brooks written?
H. K. Brooks has written: 'Rate of solution of limestone in the karst terrane of Florida' -- subject(s): Erosion, Karst, Limestone
How do stalactites in limestone caverns most likely form?
The limestone caverns themselves are formed by groundwater gradually dissolving the limestone rock. In this process, some of the limestone is taken into solution, and under favourable conditions, it will form a drip on the roof of a cavern. This may eventually build to form a stalactite above, and perhaps also a stalagmite below it.

What happens when a dilute solution of hydrochloric acid is poured on a limestone rock?
When hydrochloric acid is poured on limestone rock, a chemical reaction occurs where the acid dissolves the limestone, releasing carbon dioxide gas. This reaction forms calcium chloride and water as products. Over time, the limestone will be eroded by the acid.
What does dilute hydrochloric acid do to limestone?
Dilute hydrochloric acid reacts with limestone to form calcium chloride, carbon dioxide, and water. This reaction causes the limestone to break down and dissolve, resulting in the release of gas bubbles and the formation of a calcium chloride solution.
