Marble And Hydrochloric Acid Equation

Caco3 2hcl cacl2 h2co3.

Marble and hydrochloric acid equation.

Calcium carbonate is dissolved by hydrochloric acid thereby forming gaseous carbon dioxide. The rate of this reaction can be changed by changing the size of the marble chips. A student investigated the rate of reaction between marble and hydrochloric acid. Hydrochloric acid is hcl.

D l2 aq h2o l co2 g the student used the apparatus shown in the. In words calcium carbonate reacts with hydrochloric acid to form calcium chloride water and carbon dioxide. The reaction takes place spontaneously. Caco3 s 2hcl dt.

Marble is mostly made up of calcium carbonate which is caco3. The reaction can be represented by this equation. This experiment is to show how much carbon dioxide is produced during the reaction between an acid hydrochloric acid and marble. Calcium carbonate is dissolved by hydrochloric acid thereby forming gaseous carbon dioxide.

The student used an excess of marble. 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. Pieces of marble are thrown into hydro chloric acid. Balance the chemical equation for the reaction of calcium carbonate with hydrochloric acid.

Pieces of marble are thrown into hydro chloric acid. Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide. A strong effervescence can be observed. The combined reactants have a higher chemical potential than the combined products i e.

Marble is crystalized caco3. Marble chips are mostly made up of calcium carbonate which is a alkaline compound. Caco3 hcl cacl2 co2 h2o to balance chemical equations we need to look at each element individually on both sides of the equation. The combined reactants have a higher chemical potential than the combined products i e.

The overall reaction is 2hcl caco3 cacl2 co2 h2o. Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas. Acids carbonates salts carbon dioxide water marble is caco3 2hcl caco3 cacl2 co2 h2o.
