Abstract
The main purpose of the experiment was finding the ratio of moles of reactants in a chemical equation using the solutions with different ratio of reactants. When the volume of the resulting solution is stable, stoichiometric concentration of both reactants or the optimum ratio will lead to the full consummation of them and will result in the maximal amount of the product. In this experiment generation of heat in the course of the reaction was used to determine the optimum ratio, since the change in solution temperature is directly dependent on the amount of generated product. The comparison of the obtained results with theoretical data proved the hypothesis that this experiment can be used to determine the ratio of moles of reactants in a chemical equation.
Conclusion
The observations and calculations supported the original hypothesis, that the temperature changes measurements can be used to find the optimum ratio of moles of reactants. In the course of the conducted research I have learned how to develop an experiment to support your hypothesis and how to determine the ratio of the reactants in the solution using simple available equipment. I have also polished my skills in making conclusions on the basis of the obtained data, comparing it to theoretical one and finding out the reasons of the distinction. I think this experiment is a beneficial and efficient way to determine the optimal ratio of the solutions on practice, in case their chemical composition or the way they react is unknown. I think further experiments should be conducted to determine the property that can be observed with the smallest possible error.
Sources of Error
The possible sources of the error in the conducted experiment could be such data collection errors as inaccuracies in temperature measurement due to instruments resolution and human mistakes and calculation errors. The result might have also been affected by the temperature changes in the course of the reaction caused by environmental factors.
