What happens when acid reacts with limestone? | Questions ...
Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more acid, two hydrogen ions will

What is the characteristic of limestone? - Quora
Answer (1 of 4): Limestone is a collective term for a group of sedimentary rocks that consist of at least 50 percent calcite, a mineral formed of calcium carbonate. If some of the calcium becomes replaced by magnesium, the resulting calcium magnesium carbonate rock is called dolomitic limestone. ...
Limestone - Sedimentary rocks
Limestone is a very common sedimentary rock consisting of calcium carbonate (more than 50%). It is the most common non-siliciclastic (sandstone and shale are common siliciclastic rocks) sedimentary rock.Limestones are rocks that are composed of mostly calcium carbonate (minerals calcite or aragonite). Carbonate rocks where the dominant carbonate is dolomite (calcium magnesium carbonate) are ...

How does weathering affect limestone? - Internet Geography
Weathering is the breakdown of rock by physical, chemical or biological processes. Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone. This causes the limestone to dissolve. Carbon dioxide from the respiration of animals (and ourselves) is one cause of increased carbon dioxide in the atmosphere.
Cavern Geology
limestone. The dissolved limestone (calcium carbonate) is added to the solution, now creating calcium bicarbonate (the mixing of two carbon compounds). In the process of becoming calcium bicarbonate, the solution becomes somewhat pressurized and warms up. When it reaches the open air, the pressure is relieved by releasing the carbon dioxide.
Limestone - Wikipedia
Limestone is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3). Dolomite, CaMg(CO 3) 2, is an uncommon mineral in limestone, and siderite or other carbonate minerals are rare. However, the calcite in limestone often contains a few percent of magnesium.Calcite in limestone is divided into low-magnesium and high-magnesium ...

Limestone is an organic sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). Most limestone is composed of skeletal fragments of marine organisms such as coral, forams and molluscs. Limestone makes up about 10% of the total volume of all sedimentary rocks.

Block no. 1 contains high-quality limestone and has relatively desirable geological and tectonic conditions as well as joints and cracks. As seen in Table 3, the final F 80 is 658.24 mm, which is very close to the entrance of the crusher, i.e. 60 cm. Therefore, the suitable blasting conditions in this block could be identified based on figures resulted from analyses.
What is the limestone's mining process? - Quora
Answer: Limestone deposits are found throughout the world. They are "mined" in a process known as "quarrying." This process varies depending on the use of the product. If it is to be made into cement, it is needed in small pieces so that it can be ground and calcined. In this case, the rock has h...

How do you recognize limestone and marble? [USGS]
How do you recognize limestone and marble? The main difference between limestone and marble is that limestone is a sedimentary rock, typically composed of calcium carbonate fossils, and marble is a metamorphic rock. Limestone forms when shells, sand, and mud are deposited at the bottom of oceans and lakes and over time solidify into rock.

When sulfurous, sulfuric, and nitric acids in polluted air and rain react with the calcite in marble and limestone, the calcite dissolves. In exposed areas of buildings and statues, we see roughened surfaces, removal of material, and loss of carved details. Stone surface material may be lost all over or only in spots that are more reactive.
