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 number of 12, which belongs to the group 2 alkali metal group; it therefore has only two orbiting electrons and is very unstable and reactive. Hydrochloric acid is a solution of hydrogen and chloride a colourless acidic gas in water, Hydrochloric Acid has a high acidity and therefore will react...
tests with the gas syringe, if I would have been able to continue this experiment further I could have produced more average results and seen if my predictions for the 1 cm piece of magnesium was correct.

We could have also varied the concentration of the acid more so, and used less or more acid to get more accurate results or results for different test situations, instead of changing the strength we could have changed the amount of acid, or the temperature of the acid, or try varying these together and see how they effect each other.
Prediction I predict that the lower the concentration of the hydrochloric acid so there is fewer particles per cm3, the slower the rate of reaction will be. This is because there will be fewer particles in the Hydrochloric acid per cm3, and the solution will be more dilute so...

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...

Hypothesis: The higher level of concentration of the sugar solution, the greater reduction of the potato cylinder will be. Prediction: I think that the higher the concentration of the sugar solution, the bigger the length difference will be. This will be because the water molecules will flow out of...

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...
