The Rate of Reaction Between Hydrochloric Acid and Marble Chips
Plan
In this experiment, I will be investigating the rate of the reaction
between Hydrochloric Acid (HCl) and marble chips. To do this, I will
change the concentration of the HCl and measure how that affects the
amount of CO2 produced during the reaction, and hence, find the rate.
I predict that when I increase the concentration, the rate of the
reaction will increase. I think this because of the particle theory.
When the concentration of the HCl is increased, there will be more HCl
particles with which the marble chips can come into contact. This will
therefore mean that as there are more particles colliding, the
reaction will occur faster and more often, as there are a higher
number of particles touching and reacting at higher concentrations of
HCl than lower ones. I also predict that when the concentration is
doubled, then that rate will double also. I think this, as when there
are twice as many particles coming into contact with each other, there
will be twice as many chances for the reaction to happen per second,
and therefore the rate (amount of CO2 produced from the reaction) will
double.
There will be a limit when this relationship will no longer be true.
It will be when there is too much HCl for the marble chips to dissolve
in. This will be when the surface area of available marble chips is
completely covered by HCl, and then more HCl is added. The rate of the
reaction will not then increase its speed, as there is no more marble
chip for the HCl to actually reach.
To investigate this reaction, I need to make sure that a fair test is
used, or else my results would be inaccurate. The only variable I may
change is the concentration of HCl. I must keep all other variables,
such as the temperature, size and surface area of the marble chips,
volume of HCl, method, and the apparatus used the same.

Rate of Reaction Between Marble Chips and Hydrochloric Acid. The aim of this experiment is to find out how different variables affect the rate at which the reaction between Marble chips (CaCO ) and Hydrochloric acid (HCl) is used. There are many variables that affect the rate of this reaction such as the following. 1.

Rate of Reaction Between Calcium Carbonate and Hydrochloric Acid Plan: In my experiment I will measure the rate of reaction between calcium carbonate and hydrochloric acid. The rate of the reaction is the speed that the reaction takes place so by measuring the rate I will measure the amount of time the reaction takes. Hydrochloric acid is a strong acid that is found in digestive juices in the stomach, it is also used for cleaning metals before they are coated. Calcium carbonate has a few forms including chalk and limestone the main use of these two materials is in the making of concrete, which is used for many things such as buildings. When you put calcium carbonate and hydrochloric acid together they react to form calcium chloride, carbon dioxide and water.

Rate of Reaction - Sodium Thiosulphate and Hydrochloric Acid. Aim Investigation, to find out how the rate of reaction between sodium thiosulphate and hydrochloric acid is affected by changing the concentration. Introduction I must produce a piece of coursework investigating the rate of reaction, and the effect different changes have on them. The rate of reaction is the rate of loss of a reactant, or the rate of development of a product during a chemical reaction. It is measured by dividing 1 by the time taken for the reaction to take place.
