Marble And Acid Reaction

Finding the rate of reaction of marble chips and hydrochloric acid changing the surface area duration.

Marble and acid reaction.

How does this happen. A chemical reaction equation 9 between calcium carbonate and sulfuric acid the primary acid component of acid rain results in the dissolution of caco 3 to give aqueous ions which in turn are washed away in the water flow. In exposed areas of buildings and statues we see roughened surfaces removal of material and loss of carved details. Marble s reaction to hydrochloric acid.

Sulphuric acid is a compound it is not sulfur dioxide and water the formula is h2so4sulphuric acid is the product of the chemical reaction that occurs when sulfur trioxide and water are mixed. Stone surface material may be lost all over or only in spots that are more reactive. If the acid only makes the rock wet wipe the rock with a paper towel and go back to homogeneous looking rocks. How does acid precipitation affect marble and limestone buildings.

12 marble samples buffered solutions of ph 4 5 and 6 900 ml each 900 ml. Prediction when the concentration of acid increases more gas will be given off faster. Although these are recognized as highly durable materials buildings and outdoor monuments made of marble and limestone are now being gradually eroded away by acid rain. This experiment is to show how much carbon dioxide is produced during the reaction between an acid hydrochloric acid and marble.

Powdered marble reacts with hydrochloric acid to release bubbles of carbon dioxide gas. When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves. Change in mass of marble samples marble sample with application of distilled water ph 4 5 6 and distilled water materials. The balanced equation is.

Wipe all acid off the rock sample with a paper towel. If the acid fizzes on your sample your rock is probably marble. Marble chips and hydrochloric acid rates of reaction planning aim to find if changing the concentration of an acid will increase or decrease the rate of the reaction when marble is dissolved in hydrochloric acid.
