    What happens when acid reacts with limestone?

    15/06/2008· 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. Or, if there is more acid, two hydrogen ions will

    Limestone/Steel Interaction Metal and Metallurgy

    10/09/2006· Limestone is naturally alkaline, so corrosion will be an issue. Just coat the steel in a good epoxy prior to the veneer stone being installed. Also, are you cementing or mortaring the stone into place. Ordinary cement or concrete won't last as long as a good "flexible" polymerized thinset mortar. Good luck.

    Corrosive Water Problems

    However, the by-products of corrosion (principally copper and lead) do have drinking water standards. Copper has a secondary drinking water standard of 1.0 mg/L because it causes a bitter, metallic taste to water and a blue-green stain in sinks and bathtubs. Copper also has a primary drinking water standard of 1.3 mg/L because it may cause severe stomach cramps

    Introduction School of Materials Science and Engineering

    Corrosion is defined as the destructive and unintentional degradation of a material caused by its environment. Unfortunately for metals almost all environments can cause corrosion to some degree, since the corroded state is the more stable state. A common type of corrosion is rust, which is found on iron and steel structures. In this type of corrosion, the iron is reacting with oxygen to form

    Corrosion Protection & Resistance: Conditions

    Corrosion is often associated with a combination of elevated sulfate or chloride content in the soil in conjunction with poor drainage, a soil having considerable capacity to hold moisture, and a moderate to heavy annual rainfall (usually more than 76 cm [30 in.]). Elevated concentrations of sulfate or chloride or both in the soil are probably the primary factor in the underground corrosion
