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.
For this investigation I am reacting magnesium ribbon Mg with Hydrochloric acid HCl I am measuring the rate of reaction between the two, and to do this am measuring the hydrogen given off by the reaction. Magnesium is a shiny silver coloured metal, an element with an atomic...

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...

The aim of this experiment is to determine the order of the reactivity series by investigating the thermal breakdown of metal carbonates. Hypothesis When a metal is thermally decomposed the bond between the metal and its carbonate carbon and oxygen is removed and the carbonate is released as...
