1. Plan
Aim
I am doing this experiment to find out how I can speed up the reaction rate between calcium carbonate and hydrochloric acid.
Equipment
This is the equipment I will use:
 Gas Syringe
 Glass Flask
 Calcium Carbonate
 Hydrochloric Acid
Variable Factors
The factors that could slow down or speed up this reaction are:
 The size of the Calcium Carbonate (marble) pieces – This will affect how fast the acid reacts with the marble, the smaller the pieces, the bigger the surface area so the reaction can take place faster.
 The amount of Calcium Carbonate – The more calcium carbonate there is, the more carbon dioxide will be produced and the larger the reaction will be.
 The amount of Hydrochloric Acid – The more hydrochloric acid there is, the more carbon dioxide will be produced and the larger the reaction will be.
 The temperature of the materials – The temperature of the materials determines how fast the reaction will take place. The hotter the materials, the faster the reaction and vice-versa.
 The concentration of Hydrochloric Acid – The higher the concentration (strength) of the acid, the faster it will react.
 The purity of the Calcium Carbonate pieces – The purity of the calcium carbonate will affect the speed of the reaction also.
Prediction
From previous experiments I have learned that if large pieces are broken into smaller pieces they react faster because they have more surface area. This is because at the molecular level, there are more molecules at the surface of the chips for the molecules of acid to react with when the chips are broken into smaller pieces. The same principle can be applied to the marble chips. The smaller the chips the more surface area so I predict that the smaller marble chips will react faster than the larger chips.
Method
Here is the set up:
In this experiment I will be keeping the variables I mentioned earlier the same except one to keep the experiment fair. I will be changing the size of the marble chips to see which size reacts the fastest.
The gas syringe is firstly clamped to the stand and a plastic tube and bung are attached to the syringe.
If the amount of baking soda is increased, then the amount of carbon dioxide produced will also increase up to a certain point, at which the amount of carbon dioxide will remain constant because the vinegar has become the new limiting reactant.
If the solution is stirred more there are more collisions between the particles. therefore the reaction is speeded up). Temperature of Water - °C. As the temperature increases so does the rate of the reaction. By increasing the temperature, particles move.

Investigating the Rate of Reaction Between Marble Chips and Hydrochloric Acid I am investigating the rate of reaction between marble chips (calcium
The more concentration or more volume there is of an acid, the more acid. molecules there are that can react with the chalk. The larger the surface area of a solid, the more surface there is for acid to collide. with and react with. Higher pressure pushes the molecules closer.
The reason I believe this is that chemical reactions occur when particles of the reacting substances collide. Increasing the number of the particles increases the number of collisions per second and this increases the reaction rate. In the reaction between hydrochloric acid and calcium carbonate you can increase the number of particles in two ways. The first of these is to increase the surface area of the calcium carbonate.
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.
the reaction; if it speeds it up, slows it down or changes it in any
You can speed up the reaction by stirring the solution. 8. You can also change the rate of the reaction by adding a catalyst, which is something that speeds up the reaction. In my experiment I will change the temperature of the hydrochloric acid. I will not change anything else; I will keep the amount of calcium carbonate, the form of calcium carbonate, the concentration of hydrochloric acid, the surface area of the calcium carbonate and the amount of hydrochloric acid all the same.
If there is not enough energy no reaction takes place. In a solution of 0.5M hydrochloric acid, there are less hydrochloric acid particles compared to that of 2M hydrochloric acid, therefore, there are less particles to react with magnesium particles thus meaning less chance of collisions between the two reactants: [IMAGE] Therefore, as the concentration of the hydrochloric acid is increased, the chances of collisions increase thus giving a faster rate of reaction. Apparatus: Beaker Hydrochloric acid Distilled water Measuring cylinder Pipette Test tubes Test tube rack Diagram: [IMAGE] Method: Measure out 10cm3 of hydrochloric acid, as the concentration requires, for each concentration its composition is: Moles Volume HCl Volume Water 2M 10 cm³ 0 cm³ 1.5M 7.5 cm³ 2.5 cm³ 1M 5 cm³ 5 cm³ 0.5M 2.5 cm³ 7.5 cm³ 0M 0 cm³
Many factors influence rates of chemical reactions. Some of these factors include: the nature of reactants, for example the formation of salts, acid-base reactions, and exchange of ions are fast reactions, while in reactions where bigger molecules are formed or break apart are typically slow; temperature, frequently, the higher the temperature, the faster the reaction; concentration effect, the reliance of reaction rates on concentrations are called rate laws. Rate laws are expressions of rates in terms of the concentra...
Conclusion This experiment was set out to find the effect of different temperatures of hydrochloric acid on the rate of reaction with magnesium. The information recorded was then interpreted and compared to the hypothesis. From this information, a conclusion can be made to show that the rate of reaction relates to temperature in the reaction between hydrochloric acid and magnesium. In conclusion, as proven in this experiment, the higher the temperature of hydrochloric acid, the faster the reaction it has with magnesium.

An investigation into how changing one variable influences the rate of reaction between marble chips and dilute Hydrochloric acid
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.
