  • Chemical Weathering ScienceStruck

    When weathering takes place as a result of chemical reactions, it is known as chemical weathering. In this process the rock disintegrates chemically as the chemicals in the atmospheric agents react with the chemicals of the rock and the resultant reaction brings about the weathering of the rock.

  • Cave Formation People Pages: Faculty and Staff Websites

    To form acid rain, carbon dioxide gas reacts with water vapor and forms carbonic acid. The carbonic acid in rain water reacts with limestone as it seeps through the ground to form calcium bicarbonate in solution. In a highly jointed limestone rock, the acidic water erodes the limestone, eventually creating crevices under ground. Over time the crevices enlarge to form caves. This is the process that occurred to form .

  • Do rocks dissolve? | American Geosciences Institute

    When carbonic acid flows through the cracks of some rocks, it chemically reacts with the rock causing some of it to dissolve. Carbonic acid is especially reactive with calcite, which is the main mineral that makes up limestone.

  • When acidic rain water reacts with limestone : geology

    CaCO3 (principal component of limestone) and other carbonates (I am sure there are some organic compounds as well) act to buffer low pH waters through formation of bicarbonate. With respect to Carbonic Acid (the most common of the three) the reaction is: H2CO3 + CaCO3 <> Ca2+ + 2HCO3.

  • What Is Chemical Weathering? With Examples | Science Trends

    In limestone, which is rich in calcium carbonate, the carbonic acid, from the rainfall, reacts with the calcium carbonate in the limestone. This creates calcium bicarbonate. Limestone is slowly dissolved and becomes weathered overtime as this process continues.

  • What Are the Chemical Reaction Equations for Acid Rain ...

    The chemical reaction equation for the production of acid rain resulting from sulfur oxides is: SO 2 + HOH > H 2 SO 3. The reaction equation for acid rain produced from nitrogen oxides is: 2NO 2 + HOH > HNO 2 + HNO 3. Acid rain refers to any kind of precipitation that transports nitrogen and sulfur compounds to the Earth's surface.

  • Rate of reaction for limestone and citric acid. SlideShare

    Chemical reactions take place at very different rates – some are very fast (like explosions) and others may take months or years to proceed. In a chemical reaction which produces a gas the rate can be measured by determining the volume of gas produced as time passes. Limestone produces carbon dioxide gas when it reacts with an acid.
