Marble Chips Hydrochloric Acid Experiment

A conical flask contains the marble chips hydrochloric acid and the water that will make the reaction.

Marble chips hydrochloric acid experiment.

This reaction between marble chips calcium carbonate and hydrochloric acid is an exothermic reaction. Using the apparatus shown the change in mass of carbon dioxide can be measure with time. Measure mass of marble chips stated mass. Add acid to marble or marble to acid in a suitable container eg flask beaker boiling tube test tube.

A stand to hold up the measuring cylinder. Pieces of marble are thrown into hydro chloric acid. Secondly weight out 3 grams of marble chips for each concentration 3. Place the whole apparatus on a balance and find its mass.

An investigation of the reaction between marble chips and hydrochloric acid. Marble chips calcium carbonate caco 3 react with hydrochloric acid hcl to produce carbon dioxide gas. These are reactions that transfer energy to the surroundings. A tube to connect the conical flask to the measuring cylinder.

First you measure out 25cm3 of hydrochloric acid 2. Sample question 1 foundation. Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim. Calcium chloride solution is also formed.

The variables that i shall be changing will be the concentration of hydrochloric acid and water. 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. Add 20g of marble chips.

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. Place 40cm 3 of hydrochloric acid in an conical flask. The rate of reaction increases. The energy is usually transferred as heat energy causing the reaction mixture and its surroundings to become hotter.

Collect the gas in a gas syringe measuring cylinder over water or bubble gas. 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.
