Marble Hcl Reaction

This is because there will be more hydrochloric acid particles to collide with the marble chip particles.

Marble hcl reaction.

The reaction takes place spontaneously. Marble is crystalized caco3. Marble chips are mostly made up of calcium carbonate which is a alkaline compound. 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.

In fact if you take baking soda which contains hco3 and add vinegar which donates h to the solution this is precisely what happens. There are many variables that affect. Pieces of marble are thrown into hydro chloric acid. Marble reaction with hydrochloric acid drop a small amount of dilute hydrochloric acid on an area of your sample that has been scratched by a nail.

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. The higher the concentration of hydrochloric acid in the beaker the faster the reaction will take place. The increased h increases the rate of the reverse reactions forming carbon dioxide and water. Therefore resulting in a quicker reaction.

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. The overall reaction is 2hcl caco3 cacl2 co2 h2o. Calcium carbonate and hcl.

Hydrochloric acid or hcl is a strong acid that donates h to water. Marble is calcium carbonate and thus behaves in the same way. Caco3 s 2hcl aq 61614. Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide.

Detailed description pdf video mpg4. This process is based on random particle movement. The combined reactants have a higher chemical potential than the combined products i e.
