The Effect of Changing Concentration of Hydrochloric Acid on Its Reaction with Carbon Dioxide
Plan
Carbonates, including all forms of limestone, react with hydrochloric
acid to produce Carbon Dioxide:
Calcium ┼ Hydrochloric → Calcium ┼ Water ┼ Carbon
Carbonate Acid Chloride Dioxide
I'm going to experiment with changing the concentration of the
hydrochloric acid in this reaction and seeing how it affects the
amount of Carbon Dioxide that is produced. I predict that the amount
of Carbon Dioxide will increase as the acid is more concentrated. The
ideas behind this prediction are that a high concentration acid will
have more particles, so there will be more chance of collision between
particles and therefore a faster reaction.
The equipment I am going to use is listed here:
* Small marble chips (calcium carbonate)
* Hydrochloric acid
* Water
* Scales (to weigh marble chips)
* Measuring cylinder (to measure the hydrochloric acid/hydrochloric
acid and water solution)
* Gas syringe (to measure the amount of carbon dioxide produced)
* Delivery tube
* Conical flask
* Stop Watch
* Retort stand

First I will measure out the marble chips (I will decide how much I
will use each time during the preliminary experiment) and hydrochloric
acid solution (This will be a 10ml mixture of water and hydrochloric
acid). This is how much hydrochloric acid and water will be used in
each experiment:

3. Add on of the following volumes of distilled water to the test tube, as assigned by your teacher: 10.0mL, 15.0mL, 20.0mL, 25.0mL, 30.0mL. (If you use a graduated cylinder, remember to read the volume from the bottom of the water meniscus. You can make more a more accurate volume measurement using either a pipette or a burette.)

Planning Firstly here is a list of equipment I used. Boiling tubes Weighing scales Knife Paper towels 100% solution 0% solution (distilled water) measuring beakers potato chips Cork borer. We planned to start our experiment by doing some preliminary work. We planned to set up our experiment in the following way.
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.
The aim is to find out if changing the concentration of the hydrochloric acid solution has an effect on the time taken for the reaction. The reaction that will take place is: Hydrochloric acid + Calcium Carbonate + Calcium Chloride + Water + Carbon dioxide 2HCl (aq) + CaCo3 (s) CaCL2 (aq) + H2O + CO2 (g). Collision theory - Collisions between reactant particles are needed. for the reaction to take place in order to form a product.
The Effect of Temperature of Hydrochloric Acid on the Rate of Reaction Between Hydrochloric Acid and Magnesium
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.
