What happens when acid reacts with limestone? | Questions

Jun 15, 2008 · 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.

Limestone and Acid Rain

This produces a solution of bicarbonate. Because surface waters are in equilibrium with atmospheric carbon dioxide there is a constant concentration of carbonic acid, H 2 CO 3 , in the water. The presence of limestone and other calcium carbonate rock in lakes and streams helps to maintain a constant pH because the minerals react with the excess

Hydrothermal mineral deposit, any concentration of metallic minerals formed by the precipitation of solids from hot mineral-laden water (hydrothermal solution). The solutions are thought to arise in most cases from the action of deeply circulating water heated by magma.

How caves form | Caves and karst | Foundations of the Mendips

Caves are formed by the dissolution of limestone. Rainwater picks up carbon dioxide from the air and as it percolates through the soil, which turns into a weak acid. This slowly dissolves out the limestone along the joints, bedding planes and fractures, some of which become enlarged enough to form caves.

The process employs lime and heat as the clarifying agents. Milk of lime (about one pound per ton of cane) neutralizes the natural acidity of the juice, forming insoluble lime salts. Heating the lime juice to boiling coagulates the albumin and some of the fats, waxes, and gums, and the precipitate formed entraps suspended solids as well as the

Origin of Limestone Caves | The Institute for Creation

Although solution was a major process in the formation of limestone caves, some major problems are encountered if these caves are considered to have formed only by solution. The first problem is the origin of the original fracture porosity along which circulation of acidic groundwater could be initiated.

Seven Steps for Effective Problem Solving in the Workplace

Let me say that again. The most common mistake in problem solving is trying to find a solution right away. That's a mistake because it tries to put the solution at the beginning of the process, when what we need is a solution at the end of the process. Here are seven-steps for an effective problem-solving process. 1. Identify the issues.

Solution cavities in limestone may be completely water filled. This is called the phreatic zone. Water in the phreatic zone may be relatively still (nothephreatic), or it may be moving quickly under pressure (dynamic phreatic). Still phreatic conditions result in three-dimensional solution, forming either: large dome-shaped chambers or
