Titrations Introduction: In this experiment we are going to be testing to see which antacid tablet works the best in helping us get rid of stomache aches. From our preliminary experiment, the results we got told us that Rennie was the best antacid tablet with the most accurate results and was also the best tablet in strength. Neautralisation basically occurs when the right amounts of acid and alkaki react. Aim: The aim of this experiment is to find out which antacid tablet works the best in removing stomache aches the quickest. Key Factors: In...
weights and by taking 1g pf each tablet our results would be fair.
weights and by taking 1g pf each tablet our results would be fair.
To make our method more accurate we could test each tablet on people who have stomache aches and see which one is more effective. We could also test the pH of a stomache and see which tablet would be most suitable.
Another improvement to our experiment would be to get slices of the stomache and let it grow to see what happens and then test the tablets. We could also do the test more times and see if we get the same results.
Planning and observation Theory: in this part of the coursework I will explain the theory on rates of reactions trying to see which factors affect the speed of a reaction. If a reaction is to take place between two reactants collision needs to take place very frequently. Particles are...

The variable that I am going to base my investigation on is the concentration of hydrochloric acid. The concentration of acid is when you change the strength or the weakness of the acid. The concentrations of the acids are measured in moles for example 0.25moles, 0.5moles, 1mole and...

Prediction and scientific theory: I predict that my results will show that as the concentration of Copper Sulphate CuSO4 increases so will the current passed through the circuit. Here is a small sketch on what I think may happen. I made the above prediction using the...

Electrochemistry ?é?À Electrolytic cells An electrolytic cell is one where a non-spontaneous reaction occurs due to an external electric force placed on the cell. These are just volatic cells run backwards: for example, the reaction ?é?À Zns + Cu+2aq -> Zn+2aq + Cus E0 = 1.101 V...
