CaCO3 + 2HC1 → CaC1 + H2O + CO2
Increasing the temperature of a reaction increases the rate of a reaction. At the higher temperatures reactant particles move faster and collide more often and more violently.
After I have carry out my experiment my prediction will be if you concentrations the reaction the chemical reaction will be faster. The calcium carbonate in this reaction is usually in the form of marble chips. As the reaction happens, carbon dioxide gas is produced. There are two possible ways to measure how fast the reaction is happening. I would be starting the prediction to see the chemical reaction that is going to be taking place. As the reaction take place the oxygen started to be produce.
This is because the temperature will increase and when it does the reaction will speed up. Increasing the concentration of reactants increases the rate of a reaction. This is because there are more particles in the same volume so more collisions are possible every second.
Factors affecting the rate of a reaction: Increased temperature will make the reaction go faster. When you increase the temperature the particles will collide more effectives collision. Increase surface area, when the surface is A B the rate of the reaction will increase. I will keep the total volume of sodium thiosulphate at a constant 50cm3. I will also keep the hydrochloric acid at a constant 5cm. I will try and keep the light as constant as possible by always have a fluorescent tube light lit above the experiment to keep visibility to a maximum.
To make a fair test I would use sodium thiosulphate and hydrochloric acid. I would be measuring how high the concentration reacts with the chemical. I would also recall how many minutes it take for the reaction to take place. I would be using equipment like flask, sodium thiosulphate, gas syringes, stopcock, and dilute hydrochloric acid, and a paper mark X on it.
To make this experiment safe I would be using gurgle to make shore it does not get in contact with the eye. I would also be using dilute hydrochloric acid so if it spilt on you there would be no hazard.
I will collect the equipment conical flask, stopcock, sodium, measuring cylinder, , and gas syringes. I will measure thiosuphate into a conical flask using 100M measuring cylinder. I will Measure 5M of hydrochloric acid using 10M measuring cylinder. Draw a cross on a piece of paper place the conical flask on it. Take temperature using the monometer mix together and start the clock.
My investigation have prove that there is a chemical reaction and it has taking place during the experiment.
