Errors And Trigonometry

After processing the data to find the mass of sodium bicarbonate as well as calculating the percent errors, standard deviation and etcetera, many trends and discussion topics arose and the data produced had small calculations. The percent error showed scattered results. When looking at the table, the percent errors can go from 7.05% to 200% and the reason for the extremely high percents were systematic errors made while measuring vinegar or other measurements. Two of the three deformities in measurements come consecutively after each other: trial 6 and 7. Although three of the percent errors show the high percent, most stayed below 20% which is still not sufficive but it represents a trend in percent errors. In contrast, the standard deviation …show more content…
With the new calculated average of 1.843 grams, the experimental value becomes closer than before. Other than the reasons for error stated above and the corrections made by these error, different external factors played a role on the data. One important factor could have been the impurity of the given material of the tablet. It was not determined the age of the tablet and the state of chemical species within; if the tablet was old, some of the chemicals could have deteriorated over time. The age factor affecting the chemical species prevalence can be seen in other experiments such as the calcium titration lab, which in that case had the factor of calcium being deteriorated by light, temperature and other factors ultimately occurring overtime. It is unknown if the prevalence of age in the calcium titration lab is just as much prevalent in this lab however further research and experiments can be conducted in order to test the prevalence of this possible issue and ultimately fix final calculations of sodium
