The rate at which Alka-Seltzer tablets reacts with water Essay examples

The range at which Alka-Seltzer tablets reacts with body of waterStatement of problemThe aim of the experimentation is to find out the rate at whichAlka-Seltzer tablets react with water. The input variable that I willchange is temperature. The output variable will be noticed by thetime it takes for the Alka-Seltzer tablets to dissolve.Input variablesIn this experiment there are two main factors that can affect the rateof the reaction. These key factors can change the rate of the reactionby either change magnitude it or decreasing it. These were considered andcontrolled so that they did not disrupt the success of the experiment.Temperature- As the temperature increases, the blendments of moleculesalso increase. This is the kinetic theory. When the temperature isincreased the particles gain more energy and therefore move aroundfaster. This gives the particles more of a chance with other particlesand with more force.The increase in temperature will therefore increase the rate ofr eaction.As this is the variable I am measuring I will not keep the temperatureconstant and therefore I will be varying it.Volume of water- if the pile of the water is increased there is morelikelihood that there will be more collisions. This is because thereare more water molecules in a effrontery volume to react with theAlka-Seltzer tablets. However if there are sufficient water moleculesto occupy the Alka-Seltzer tablets an increase in the water moleculeswill not alter the rate of the reaction. This is because theAlka-Seltzer tablets are already working as fast as they can to reactwith the water.The concentration can be increased by increasing the volume of thewater use in the reaction to dissolve the Alka-Seltzer tablets in.To control the... ... different from what it should be. To solvethis problem a thermostatic water bath could be used as statedabove.* If the stop watch was stopped to early or late, again the overallreading would not be as accurate as it could have been.* I t was almost impossible to tell when the Alka-Seltzer tablet haddissolved, each time the experiment was done. This was a hugeproblem for the experiment as this could have all causedproblems to the experiment. A special type of detector apparatus,which bleeped when the correct amount of Alka-Seltzer tabletdissolved, could improve this, each time the experiment was done.This would give us an extra measure of accuracy each time.Another way to improve the experiment and to produce consistentreadings was to used distilled water. This is because the distilledwater contains no impurities and therefore no hardness in water.
