Marble Reacting With Hydrochloric Acid Equation

Pieces of marble are thrown into hydro chloric acid.

Marble reacting with hydrochloric acid equation.

The chemical equation that is going to be followed throughout the experiment will be. Hydrochloric acid to react with the marble chips independent variable marble chips to react with the acid dependent variable stopwatch to accurately time the experiment spatula to handle the marble chips measuring cylinder to precisely measure out different concentrations of hydryochloric acid electric balance to measure the mass g of the marble chips bung. The combined reactants have a higher chemical potential than the combined products i e. Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide.

Click each image to see positive and negative results of the acid test. The reaction takes place spontaneously. Marble is especially sensitive to the degrading by acidic chemicals also to weathering. Marble chips are mostly made up of calcium carbonate which is a alkaline compound.

In exposed areas of buildings and statues we see roughened surfaces removal of material and loss of carved details. Hydrochloric acid is hcl. This experiment is to show how much carbon dioxide is produced during the reaction between an acid hydrochloric acid and marble. Caco3 2hcl cacl2 h2co3.

Acids carbonates salts carbon dioxide water marble is caco3 2hcl caco3 cacl2 co2 h2o. Acid rain is one of the top degradation agents for marble artefacts around the world. When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves. H2co3 decomposes easily into h2o and co2 so the equation is.

In words calcium carbonate reacts with hydrochloric acid to form calcium chloride water and carbon dioxide. Drop a small amount of dilute hydrochloric acid on an area of your sample that has been scratched by a nail. I marble chips are made from calcium carbonate hydrochloric acid calcium carbonate calcium chloride water carbon dioxideii the rate of reaction can be increased by increasing the concentration of hydrochloric acid which is the limiting factor in this equation. Acid rain contains carbonic acid nitric acid and sulphuric acid co2 no2 and so2.

Marble is mostly made up of calcium carbonate which is caco3. Powdered marble reacts with hydrochloric acid to release bubbles of carbon dioxide gas. Stone surface material may be lost all over or only in spots that are more reactive. Calcium carbonate is dissolved by hydrochloric acid thereby forming gaseous carbon dioxide.
