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

The number at which Alka-Seltzer tablets fights with waterStatement of worryThe aim of the experiment is to find out the rate at whichAlka-Seltzer tablets react with water. The input variable quantity that I exitchange is temperature. The output variable will be measured by the sequence it takes for the Alka-Seltzer tablets to dissolve.Input variablesIn this experiment thither are two main factors that mint simulate the rateof the reaction. These key factors can change the rate of the reactionby either change magnitude it or decreasing it. These were considered and insureled so that they did not crack up the success of the experiment.Temperature- As the temperature accessions, the movements of moleculesalso increase. This is the kinetic theory. When the temperature isincreased the particles gain more energy and at that placefore move aroundfaster. This gives the particles more of a fall out with other particlesand with more force.The increase in temperature will therefor e increase the rate ofreaction.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 mint of the water is increased there is morelikelihood that there will be more collisions. This is because thereare more water molecules in a given volume to react with theAlka-Seltzer tablets. However if there are sufficient water moleculesto get hold of 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 utilize in the reaction to dissolve the Alka-Seltzer tablets in.To control the... ... different from what it should be. To solvethis paradox a thermostatic water toilet could be used as statedabove.* If the stop watch was halt to early or late, again the overallreading would not be as accu rate as it could have been.* It was almost impossible to suppose when the Alka-Seltzer tablet haddissolved, each(prenominal) time the experiment was done. This was a hugeproblem for the experiment as this could have totally causedproblems to the experiment. A special casing 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.
