Marble Chips Hydrochloric Acid Experiment

Secondly weight out 3 grams of marble chips for each concentration 3.

Marble chips hydrochloric acid experiment.

Using the apparatus shown the change in mass of carbon dioxide can be measure with time. Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim. Place a loose plug of cotton wool in the neck of the flask to prevent acid spray escaping. Measure mass of marble chips stated mass.

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. Note the time as soon as the mass is known. Place 40cm 3 of hydrochloric acid in an conical flask.

Add 20g of marble chips. A stand to hold up the measuring cylinder. Add acid to marble or marble to acid in a suitable container eg flask beaker boiling tube test tube. An investigation of the reaction between marble chips and hydrochloric acid.

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. Pieces of marble are thrown into hydro chloric acid. Calcium chloride solution is also formed. These are reactions that transfer energy to the surroundings.

First you measure out 25cm3 of hydrochloric acid 2. Measure volume of acid stated volume. 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.

Sample question 1 foundation. Collect the gas in a gas syringe measuring cylinder over water or bubble gas. The energy is usually transferred as heat energy causing the reaction mixture and its surroundings to become hotter. 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. Place the whole apparatus on a balance and find its mass.
