Introduction

Adam Lewis 11Mr chemistry practical In my experiment I am going to change the strength of the solution to see how this affects the rate of reaction with magnesium. Task The variables that could affect the outcome Are : - Measuring of acid, temperature of room, thickness of magnesium, if I stir it, length of magnesium, concentration of acid. I am going to keep all the variables listed above the same, except for the concentration of the acid, which the magnesium will be put in. ...read more.

Middle

Concentration The more concentrated the acid is the quicker the experiment will work, as there is more particles for something to react with. Temperature The hotter it is the quicker it will work, this is because the particles will be moving much quicker as they have more energy. Surface area The big the surface area the faster it will react as there is more area for the particles to react with there for it will work quicker. ...read more.

Conclusion

Diagram Method First of all I collected all the equipment stated in the apparatus and then set it up as shown in the diagram. Results Conclusion From this experiment I found out that it did what my prediction said and that osmosis does travel from a weak to strong solution Evaluation Over all I think that the experiment went well. One of my results was out but I think that I just got the solutions label the wrong way or mixed them up wrong. ...read more.
