Data: Vinegar in the vial number 1, lemon juice in the vial number 2, soda in the fourth one, white wine in the sixth one changed their color into light pink. It indicated that those products were examples of acids. Washing powder in the third jar, milk in the vial number five, drain cleaner in the seventh one, and shampoo in the eighth turned green; therefore, those are bases. Results: Acids and bases are opposite chemical classes, which neutralize each other. Most acids are quite corrosive so they are able to dissolve some metals. Bases can produce a reaction with acids, which results in salt and water. A generally accepted method of identifying a chemical nature of a liquid is a litmus test, and if a paper turns red or blue, the chemical is acid or base respectively.
However, an experiment with cabbage juice is productive as well as a litmus one since this juice is an efficient, simple, and affordable acid-base indicator, and when it is mixed with a certain chemical, the substance changes its color into either pink or green. In the first case, it indicates an acid, while in the second case, it determines a base. Furthermore, it is safe and inexpensive; therefore, it can be used in amateur chemical experiments at home, in a learning process in schools or colleges, or in science activities. This experiment can be used in order to prove that there are lots of examples of bases and acids in a household. Formal Lab Report What Is a Lab Report?
How to Create a Lab Report? What is the aim of a lab report? What is the best way to write a lab summary? Laboratory reports are an essential component of the experimental method. They also make suggestions for future research and trials, as well as changes to current approaches. The objectives are the goals you want to achieve during the experiment. Give a quick rundown of the steps you took to complete the experiment. Give a summary of the research to make the reader understand what you did. Take instant records of everything that happens during the experiment in your lab notebook. Never rely on your memory! This function should be fulfilled in the sections Discussions or Analysis sections, which should come right afterwards.
Your conclusion makes a brief summary. It should consist of sentences, not many more. Restate your hypothesis in other words. It is extremely common in chemistry to find yourself on this kind of situations! You only need to be able to explain why you got the results that you got, and how would you go around to fix them! You should also obligatorily use some secondary sources to support your theory. Therefore, you have to cite and make references according to the assigned writing format. The final step is to proofread your lab report. Write each section properly to receive the highest grades for your experiment.
Always be clear, cite the appropriate references, and be objective with your analysis and conclusions! Your email address will not be published. This site uses Akismet to reduce spam.

The purpose of the laboratory was to investigate the percentage of Aspirin in different brands of pain medications. Many different companies have used this chemical in their medication products. The goal of the study was to compare the percentage of aspirin in each product through a method of reacting aspirin acetylsalicylic acid with sodium hydroxide using the following equation:. The aspirin tablets were weighed using a balance, placed into the 50cm3 conical flask, and dissolved in The solution was titrated with 0. Referring to the equation above, the Molar Ratio between Aspirin and NaOH is The percentage of Aspirin in each of the tablets was calculated using the number of moles of NaOH per mole of acetylsalicylic acid C 9 H 8 O 4.
As seen in trial 1 for Bayer Aspirin, the volume of NaOH was Table 6 The number of grams of acetylsalicylic acid was calculated using the calculated number of moles for NaOH 0. In order to obtain the amount of aspirin in the solution, the number of moles is multiplied by the molar mass. For example, in Trial 1, 0. The calculations were repeated for each trial for each tablet. In addition, the average amount of acetylsalicylic acid was computed for each tablet and illustrated in Figure 2. The largest amount of acetylsalicylic acid was observed in the Countre-Douleurs Plus at 0.
Figure 1. As seen in Table 6, the percentage of aspirin in each of the tablets was computed. In addition, mean values for each tablet was calculated. The degree of error was also calculated for each trial for each of the tablets. Figure 2 The degree of error was calculated by multiplying 0. For example, in Bayer trial 1, 0. Table 7. The averages for each tablet were computed and illustrated in Figure 3. The average percent errors were less than 1. The highest percent error was observed in Bayer tablets at 0. Figure 3. The results of the experiment found that Bayer had the highest percentage of Aspirin compared to the other tablets. As seen in Figure 1, Bayer contained In addition, Bayer was the smallest tablet compared to Alka-Seltzer and Countre-Douleurs Plus.
Table 6 Furthermore, the price of Bayer was at 6. Countre-Douleurs Plus also had a similar amount of acetylsalicylic acid in the contents compared to Bayer. In regard to the Alka-Seltzer, there were some differences in the data collection in regard to the Alka-Seltzer tablet. It is possible that this may have caused some error in the data results and therefore, The differences in the percentages of aspirin in each tablet were predicted since this product is found in numerous pain relievers which contain various different substances, such as caffeine and buffers. Katz, The experiment resulted in data clearly indicating the percentages of aspirin found in three different tablets.
The problem with the design of the experiment was the samples chosen to compare. Three different products were used; however, the products used were for different types of symptoms. For instance, Bayer Aspirin is an Analgesic and used for symptoms such as head ache or fever. Alka-Seltzer, on the hand is used primarily for gastrointestinal problems. Therefore, it would be assumed that the Bayer Aspirin contains more aspirin than a gastrointestinal product. Bayer, The experiment should have used three different types of similar Aspirin products in order to compare the amount of aspirin between products for future use as a pain reliever. In addition, there was a larger different in mass between the Bayer and Alka-Seltzer, which required more sodium hydroxide in the reaction.
As far as the procedure was conducted, the methods were taken in a step-by-step methodology. The tablets were weighed and measured on a balance carefully and the titrations were measured with accuracy. The accuracy of the methods can be supported with the values computed for each trial for each tablet. In addition, the percent errors were low, suggesting the procedure was performed accurately. Three trials for each of the tablets were sufficient to calculate a mean for each of tablet in the time allotted during the laboratory session.
Investigating and comparing the differences in percentages of the different tablets of the same type of pain reliever could provide more insight into the types of aspirin one should purchase to relieve symptoms. In this case, there were not three of the same types of products; therefore, it is hard to compare the percentage of aspirin in a headache reliever versus a gastrointestinal product. In addition, using the same types of products can bring awareness to the public on which products would most likely work the best. Furthermore, cost analysis between the products can also be analyzed. In regard to the current experiment, since additional sodium hydroxide was added to the product, the experiment should have been repeated to add additional sodium hydroxide to the other sample tablets.
