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

The localize at which Alka-Seltzer pads contradicts with peeStatement of problemThe conduct of the test is to find out the pass judgment at whichAlka-Seltzer tablets answer with water. The gossip variable that I go awaychange is temperature. The output variable leave behind be measured by thetime it takes for the Alka-Seltzer tablets to dissolve.Input variablesIn this investigate there atomic number 18 two main factors that can affect the rateof the reaction. These key factors can change the rate of the reactionby either increasing it or decreasing it. These were considered andcontrolled so that they did not disrupt the achievement of the prove.Temperature- As the temperature developments, the movements of moleculesalso increase. This is the kinetic theory. When the temperature isincreased the particles gain more than capacity and therefore move aroundfaster. This gives the particles more of a chance with separate particlesand with more force.The increase in tempe rature will therefore 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 good deal of the water is increased there is morelikelihood that there will be more collisions. This is because there are more water molecules in a given 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 used in the reaction to dissolve the Alka-Seltzer tablets in.To control the... ... diametrical from what it should be. To solvethis problem a thermostatic water bath could be used as statedabove.* If the stop watch was stopped to other(a) or late, again the overallreading would not be as accurate as it could have been.* It 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 totally causedproblems to the experiment. A special type of demodulator 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. other 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.
