Marble And Hydrochloric Acid

Marble reaction with hydrochloric acid.

Marble and hydrochloric acid.

This process is based on random particle movement. Calcium carbonate is dissolved by hydrochloric acid thereby forming gaseous carbon dioxide. The overall reaction is 2hcl caco3 cacl2 co2 h2o. Calcium carbonate is dissolved by hydrochloric acid thereby forming gaseous carbon dioxide.

The combined reactants have a higher chemical potential than the combined products i e. This is the word equation for my investigation calcium hydrochloric calcium carbon water image carbonate acid chloride dioxide. Pieces of marble are thrown into hydro chloric acid. Marble chips and hydrochloric acid 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.

Click each image to see positive and negative results of the acid test. This experiment is to show how much carbon dioxide is produced during the reaction between an acid hydrochloric acid and marble. The combined reactants have a higher chemical potential than the combined products i e. 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.

Powdered marble reacts with hydrochloric acid to release bubbles of carbon dioxide gas. Pieces of marble are thrown into hydro chloric acid. The reaction takes place spontaneously. The reaction takes place spontaneously.

With the equation caco3 2hcl cacl2 h2o co2 hypotheses a reaction occurs when particles collide. Drop a small amount of dilute hydrochloric acid on an area of your sample that has been scratched by a nail. Marble is crystalized caco3.
