A chemistry investigation to look at the rates of reaction between marble chips and hydrochloric acid.
Marble and hydrochloric acid.
Powdered marble reacts with hydrochloric acid to release bubbles of carbon dioxide gas.
A strong effervescence can be observed.
Pieces of marble are thrown into hydro chloric acid.
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.
Task my task is to measure the rate of reaction between marble chips caco 3 and hydrochloric acid 2 hcl.
The combined reactants have a higher chemical potential than the combined products i e.

When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves.
Marble reaction with hydrochloric acid.
To investigate the effect of concentration on the reaction between marble chips and hydrochloric acid materials.
The overall reaction is 2hcl caco3 cacl2 co2 h2o.
This experiment is to show how much carbon dioxide is produced during the reaction between an acid hydrochloric acid and marble.
Pieces of marble are thrown into hydro chloric acid.
