Marble Hcl Reaction

Marble chips are mostly made up of calcium carbonate which is a alkaline compound.

Marble hcl reaction.

Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide. Calcium carbonate and hcl. Hydrochloric acid marble chips the experiment the aim of this experiment is to find out how different variables affect the rate at which the reaction between marble chips caco and hydrochloric acid hcl takes place. Calcium carbonate is dissolved by hydrochloric acid thereby forming gaseous carbon dioxide.

Marble is calcium carbonate and thus behaves in the same way. Marble is crystalized caco3. With the equation caco3 2hcl cacl2 h2o co2 hypotheses a reaction occurs when particles collide. Pieces of marble are thrown into hydro chloric acid.

There are many variables that affect. The reaction takes place spontaneously. Caco3 s 2hcl aq 61614. Cacl2 aq h2o l co2 g in this experiment i am going to see if temperature affects the reaction rate between marble chips and hydrochloric acid by timing the release of carbon dioxide in the reaction.

The overall reaction is 2hcl caco3 cacl2 co2 h2o. This process is based on random particle movement. Therefore resulting in a quicker reaction. 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.

Detailed description pdf video mpg4. The higher the concentration of hydrochloric acid in the beaker the faster the reaction will take place. This is because there will be more hydrochloric acid particles to collide with the marble chip particles. 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 increased h increases the rate of the reverse reactions forming carbon dioxide and water. In fact if you take baking soda which contains hco3 and add vinegar which donates h to the solution this is precisely what happens. Hydrochloric acid or hcl is a strong acid that donates h to water.
