The variables that i shall be changing will be the concentration of hydrochloric acid and water.
Marble chips and hydrochloric acid equation.
Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas.
Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim.
An investigation of the reaction between marble chips and hydrochloric acid.
Hcl calcium carbonate calcium chloride carbon dioxide water.
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.
Calcium chloride solution is also formed.
With the equation caco3 2hcl cacl2 h2o co2 hypotheses a reaction occurs when particles collide.
The rate of this reaction can be measured by looking at the rate at which the product carbon dioxide gas is formed.
A conical flask contains the marble chips hydrochloric acid and the water that will make the reaction.
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.
Using a measuring cylinder add 50 cm 3 of dilute hydrochloric acid to a conical flask.
I marble chips are made from calcium carbonate hydrochloric acid calcium carbonate calcium chloride water carbon dioxideii the rate of reaction can be increased by increasing the concentration of hydrochloric acid which is the limiting factor in this equation.
The rate of this reaction can be changed by changing the size of the marble chips.
A tube to connect the conical flask to the measuring cylinder.
Using the apparatus shown the change in mass of carbon dioxide can be measure with time.
