These are reactions that transfer energy to the surroundings.
Marble chips hydrochloric acid experiment.
Place a loose plug of cotton wool in the neck of the flask to prevent acid spray escaping.
Place 40cm 3 of hydrochloric acid in an conical flask.
As the marble chips react with the acid carbon dioxide is given off.
Calcium chloride solution is also formed.
A stand to hold up the measuring cylinder.
The rate of reaction increases.
Measure volume of acid stated volume.
Pieces of marble are thrown into hydro chloric acid.
A tube to connect the conical flask to the measuring cylinder.
First you measure out 25cm3 of hydrochloric acid 2.
Marble chips calcium carbonate caco 3 react with hydrochloric acid hcl to produce carbon dioxide 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.
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.
Add acid to marble or marble to acid in a suitable container eg flask beaker boiling tube test tube.
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.
Sample question 1 foundation.
Measure mass of marble chips stated mass.
An investigation of the reaction between marble chips and hydrochloric acid.
The energy is usually transferred as heat energy causing the reaction mixture and its surroundings to become hotter.
The variables that i shall be changing will be the concentration of hydrochloric acid and water.
Collect the gas in a gas syringe measuring cylinder over water or bubble gas.
Using the apparatus shown the change in mass of carbon dioxide can be measure with time.
A conical flask contains the marble chips hydrochloric acid and the water that will make the reaction.
Note the time as soon as the mass is known.
Secondly weight out 3 grams of marble chips for each concentration 3.
This reaction between marble chips calcium carbonate and hydrochloric acid is an exothermic reaction.
