Marble reaction with hydrochloric acid.

What does acid do to marble.

Although they look a lot like stains an etch mark is a physical alteration to the marble s surface by the acid. In exposed areas of buildings and statues we see roughened surfaces removal of material and loss of carved details. Look at the sample from all angles. A strong effervescence can be observed.

It is one of the most effective acid neutralization materials. When my husband and i were researching our kitchen renovation a couple years ago marble countertops were the clear frontrunner but we were nervous about the inevitable etching. Concentrate on fresh surfaces where you might be able to better determine the texture. Brush the acid on at a 1 10 acid water dilution and scrub with a nylon brush.

Pieces of marble are thrown into hydro chloric acid. Calcium carbonate is dissolved by hydrochloric acid thereby forming gaseous carbon dioxide. Immediately after removing rust neutralize the acid with a baking soda water paste 1 1. Any fruits or vegetables that contain acids will etch your marble.

When sulfurous sulfuric and nitric acids in polluted air react with the calcite in marble and limestone the calcite dissolves. However concrete acid stain possesses the unique property of creating a marble like effect without any additional staining techniques. Acid precipitation affects stone primarily in two ways. When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves.

The combined reactants have a higher chemical potential than the combined products i e. Stone surface material may be lost all over or only in spots that are more reactive. Common fruits and vegetables will etch your marble. Being composed of calcium carbonate marble will react in contact with many acids neutralizing the acid.

Particularly on older concrete slabs exposed to the elements the variable porosity of the slab allows the stain to penetrate to different depths creating natural areas of light and dark staining. It is used for acid neutralization in the chemical industry as well. How does acid precipitation affect marble and limestone buildings. Where as a stain occurs when foreign materials penetrate the pours in marble and leave the marble discolored.

If your rock sample does not have any of the features described on this page reexamine the rock with a hand lens or magnifying glass. Marble is often crushed and used for acid neutralization in streams lakes and soils.
