This is because there will be more hydrochloric acid particles to collide with the marble chip particles.
Marble chips and hydrochloric acid results.
The experiment involves using hydrochloric acid acidic and marble chip alkali.
As the marble chips react with the acid carbon dioxide is given off.
Using the apparatus shown the change in mass of carbon dioxide can be measure with time.
We are going to put both reactants into a chonical flask and collect the gas that will be given off.
A stand to hold up the measuring cylinder.
First you measure out 25cm3 of hydrochloric acid 2.
The rate of this reaction can be changed by changing the size of the marble chips.
With the equation caco3 2hcl cacl2 h2o co2 hypotheses a reaction occurs when particles collide.
9 3 sketch a line on the grid in figure 10 to show the results you would expect if the experiment was repeated using 20 g of smaller marble chips.
Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas.
This reaction between marble chips calcium carbonate and hydrochloric acid is an exothermic reaction.
The energy is usually transferred as heat energy causing the reaction mixture and its surroundings to become hotter.
Calcium chloride solution is also formed.
This process is based on random particle movement.
Marble chips and hydrochloric acid planning aim to find if changing the concentration of an acid will increase or decrease the rate of the reaction when marble is dissolved in hydrochloric acid.
Secondly weight out 3 grams of marble chips for each concentration 3.
Pour the acid into the conical flask and add the marble chips 5.
Describe how you could investigate.
2 marks 9 4 explain in terms of particles how and why the rate of reaction changes during the reaction of calcium carbonate with hydrochloric acid.
Marble chips calcium carbonate caco 3 react with hydrochloric acid hcl to produce carbon dioxide gas.
Therefore resulting in a quicker reaction.
A tube to connect the conical flask to the measuring cylinder.
Label this line a.
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.
These are reactions that transfer energy to the surroundings.
An investigation of the reaction between marble chips and hydrochloric acid.
Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim.
The variables that i shall be changing will be the concentration of hydrochloric acid and water.
The temperature increase can be detected using a thermometer.
A conical flask contains the marble chips hydrochloric acid and the water that will make the reaction.
