Marble Chips Hydrochloric Acid Experiment

Marble chips calcium carbonate caco 3 react with hydrochloric acid hcl to produce carbon dioxide gas.

Marble chips hydrochloric acid experiment.

Secondly weight out 3 grams of marble chips for each concentration 3. These are reactions that transfer energy to the surroundings. Calcium chloride solution is also formed. Using the apparatus shown the change in mass of carbon dioxide can be measure with time.

Pieces of marble are thrown into hydro chloric 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. This reaction between marble chips calcium carbonate and hydrochloric acid is an exothermic reaction. Place 40cm 3 of hydrochloric acid in an conical flask.

Collect the gas in a gas syringe measuring cylinder over water or bubble gas. As the marble chips react with the acid carbon dioxide is given off. Place the whole apparatus on a balance and find its mass. 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.

A conical flask contains the marble chips hydrochloric acid and the water that will make the reaction. An investigation of the reaction between marble chips and hydrochloric acid. Sample question 1 foundation. The rate of reaction increases.

Note the time as soon as the mass is known. Add acid to marble or marble to acid in a suitable container eg flask beaker boiling tube test tube. A tube to connect the conical flask to the measuring cylinder. The energy is usually transferred as heat energy causing the reaction mixture and its surroundings to become hotter.

Add 20g of marble chips. First you measure out 25cm3 of hydrochloric acid 2. Measure mass of marble chips stated mass. The variables that i shall be changing will be the concentration of hydrochloric acid and water.

Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim. A stand to hold up the measuring cylinder.
