Marble Chips Hydrochloric Acid Experiment

These are reactions that transfer energy to the surroundings.

Marble chips hydrochloric acid experiment.

Place 40cm 3 of hydrochloric acid in an conical flask. Pieces of marble are thrown into hydro chloric acid. Marble chips calcium carbonate caco 3 react with hydrochloric acid hcl to produce carbon dioxide gas. Sample question 1 foundation.

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. Collect the gas in a gas syringe measuring cylinder over water or bubble gas. Calcium chloride solution is also formed. First you measure out 25cm3 of hydrochloric acid 2.

Using the apparatus shown the change in mass of carbon dioxide can be measure with time. Add 20g of marble chips. Measure mass of marble chips stated mass. The rate of reaction increases.

Note the time as soon as the mass is known. The energy is usually transferred as heat energy causing the reaction mixture and its surroundings to become hotter. A stand to hold up the measuring cylinder. Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim.

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 volume of acid stated volume. A conical flask contains the marble chips hydrochloric acid and the water that will make the reaction. Place a loose plug of cotton wool in the neck of the flask to prevent acid spray escaping.

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. Place the whole apparatus on a balance and find its mass. As the marble chips react with the acid carbon dioxide is given off. A tube to connect the conical flask to the measuring cylinder.

The variables that i shall be changing will be the concentration of hydrochloric acid and water. Secondly weight out 3 grams of marble chips for each concentration 3.
