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.
Aim: to investigate how the rate of a reaction is affected by the surface area of the solid, the temperature or the concentration of the solution. The experiment I am choosing is to investigate how the concentration affects the rate of a reaction. The other reactions I don't...

I am measuring the rate of reaction how fast a reaction takes of sodium thiosulphate and hydrochloric acid. There are different variables I could use to see the change in the rate of reaction. These include temperature, concentration or catalysts. I am going to do two experiments, one...

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...
