Marble And Acid Reaction

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.

Marble and acid reaction.

How does acid precipitation affect marble and limestone buildings. Prediction when the concentration of acid increases more gas will be given off faster. Wipe all acid off the rock sample with a paper towel. 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.

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. 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.

How does this happen. When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves. Powdered marble reacts with hydrochloric acid to release bubbles of carbon dioxide gas. Finding the rate of reaction of marble chips and hydrochloric acid changing the surface area duration.

Change in mass of marble samples marble sample with application of distilled water ph 4 5 6 and distilled water materials. This experiment is to show how much carbon dioxide is produced during the reaction between an acid hydrochloric acid and marble. Students know buffers stabilize ph in acid base reactions. If the acid only makes the rock wet wipe the rock with a paper towel and go back to homogeneous looking rocks.

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. Stone surface material may be lost all over or only in spots that are more reactive. In exposed areas of buildings and statues we see roughened surfaces removal of material and loss of carved details.
