Marble And Hydrochloric Acid

The reaction takes place spontaneously.

Marble and hydrochloric acid. I am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the concentration is changed. Calcium carbonate is dissolved by hydrochloric acid thereby forming gaseous carbon dioxide. Pieces of marble are thrown into hydro chloric acid. With the equation caco3 2hcl cacl2 h2o co2 hypotheses a reaction occurs when particles collide.

Powdered marble reacts with hydrochloric acid to release bubbles of carbon dioxide gas. Pieces of marble are thrown into hydro chloric acid. Drop a small amount of dilute hydrochloric acid on an area of your sample that has been scratched by a nail. This process is based on random particle movement.

The reaction takes place spontaneously. Marble reaction with hydrochloric acid. 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.

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. A strong effervescence can be observed. Calcium carbonate is dissolved by hydrochloric acid thereby forming gaseous carbon dioxide. This experiment is to show how much carbon dioxide is produced during the reaction between an acid hydrochloric acid and marble.

This is the word equation for my investigation calcium hydrochloric calcium carbon water image carbonate acid chloride dioxide. Hydrochloric acid 20ml 0 5m 1m 2m marble chips 2g per test large measuring cylinder plastic bowl 3 4 full of water rubber tubing glass conical flask stopwatch method. The overall reaction is 2hcl caco3 cacl2 co2 h2o.
