Marble Chips And Acid

Measuring the rate of reaction at various times.

Marble chips and acid.

You then fill a bowl with water along with a boiling tube and straight after attach the delivery tube at the end of the boiling tube 4. The rate of this reaction can be changed by changing the size of the marble chips. This variable changes the rate of reaction by adding more acid in concentration than the water then the reaction will take place quicker because there is more acid to react with the marble chips and if you add more water then the reaction will take longer because there is less acid to react with the marble chips. Marble chips are mostly made up of calcium carbonate which is a alkaline compound.

With the equation caco3 2hcl cacl2 h2o co2 hypotheses a reaction occurs when particles collide. Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim. The reaction between sulfuric acid and calcium carbonate is somewhat similar to the reaction with sodium bicarbonate way carbon dioxide. This process is based on random particle movement.

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. Secondly weight out 3 grams of marble chips for each concentration 3. Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas. In the investigation i am going to find out how the surface area affects the rate of reaction by measuring the amount of gas produced and weight loss in a reaction between small large pieces of marble chips calcium carbonate and hydrochloric acid per minute.

Pour the acid into the conical flask and add the marble chips 5. Marble is calcium carbonate and thus behaves in the same hydrochloric acid calcium carbonate calcium chloride carbon dioxide water. Describe how you could investigate. Calcium carbonates which are marble chips react with hydrochloric acid to give out calcium chloride water and carbon dioxide.
