Marble Chips Hydrochloric Acid Experiment

First you measure out 25cm3 of hydrochloric acid 2.

Marble chips hydrochloric acid experiment.

These are reactions that transfer energy to the surroundings. Add acid to marble or marble to acid in a suitable container eg flask beaker boiling tube test tube. Pieces of marble are thrown into hydro chloric acid. A tube to connect the conical flask to the measuring cylinder.

Note the time as soon as the mass is known. Collect the gas in a gas syringe measuring cylinder over water or bubble gas. Calcium chloride solution is also formed. Place the whole apparatus on a balance and find its mass.

Sample question 1 foundation. This reaction between marble chips calcium carbonate and hydrochloric acid is an exothermic reaction. The variables that i shall be changing will be the concentration of hydrochloric acid and water. The rate of reaction increases.

Acid rain experiment with marble chips and hydrolic acid higher the concentration of hydrochloric acid the faster the reaction will take place because there will be more hydrochloricacidparticles to collide with the marblechipparticles therefore resulting in a quicker reaction. Marble chips calcium carbonate caco 3 react with hydrochloric acid hcl to produce carbon dioxide gas. As the marble chips react with the acid carbon dioxide is given off. Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim.

The energy is usually transferred as heat energy causing the reaction mixture and its surroundings to become hotter. A conical flask contains the marble chips hydrochloric acid and the water that will make the reaction. 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. Measure mass of marble chips stated mass.

Add 20g of marble chips. Place a loose plug of cotton wool in the neck of the flask to prevent acid spray escaping. A stand to hold up the measuring cylinder. Measure volume of acid stated volume.

An investigation of the reaction between marble chips and hydrochloric acid. Using the apparatus shown the change in mass of carbon dioxide can be measure with time.
