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. Powdered marble reacts with hydrochloric acid to release bubbles of carbon dioxide gas. Students know buffers stabilize ph in acid base reactions. Marble is mostly calcium carbonate caco3 so when it react with nitric acid hno3 the products will be calcium nitrate carbon dioxide which effervesces and water.

The balanced equation is. 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. When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves. If the acid fizzes on your sample your rock is probably marble.

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. How does acid precipitation affect marble and limestone buildings. 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.

12 marble samples buffered solutions of ph 4 5 and 6 900 ml each 900 ml. Bournemouth school for girls 15 693 views. Wipe all acid off the rock sample with a paper towel. 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.

This experiment is to show how much carbon dioxide is produced during the reaction between an acid hydrochloric acid and marble. If the acid only makes the rock wet wipe the rock with a paper towel and go back to homogeneous looking rocks. Stone surface material may be lost all over or only in spots that are more reactive.
