This process is based on random particle movement.
Marble and hydrochloric acid.
The reaction takes place spontaneously.
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.
With the equation caco3 2hcl cacl2 h2o co2 hypotheses a reaction occurs when particles collide.
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.
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.
Click each image to see positive and negative results of the acid test.
The overall reaction is 2hcl caco3 cacl2 co2 h2o.
Drop a small amount of dilute hydrochloric acid on an area of your sample that has been scratched by a nail.
Pieces of marble are thrown into hydro chloric acid.
Marble is crystalized caco3.
This is the word equation for my investigation calcium hydrochloric calcium carbon water image carbonate acid chloride dioxide.
Calcium carbonate is dissolved by hydrochloric acid thereby forming gaseous carbon dioxide.
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.
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.
Pieces of marble are thrown into hydro chloric acid.
