PH Determination of Solutions - Lab Report Example The pH of the solution in each test tube was then measured using a pH meter and the value was recorded. Thereafter, two to three drops of the universal indicator were added to the solution in each test tube and the resultant color was noted and read against the matching color and pH on the universal indicator chart. A similar procedure was repeated for the basic solutions in four different test tubes labeled 10, 11, 13, and 14. The colors of the solutions and the resultant pH using the pH meter as well as the universal indicator were recorded and comparisons were made. In comparing the pH of various acidic and basic solutions using a pH meter and universal indicator, the color, pH of universal indicator and pH from the ph meter was recorded for each solution. Table 1 below summarizes the observed results for the acidic solutions. It was observed that the pH obtained from the pH chart varied from the pH obtained from the pH meter in most of the solutions. The variations were small in some of the solutions such as1, 3 and 13. On the other hand, the variations in pH were significant in solutions such as 4, 7, 10 and 11. The pH meter value was the same as the universal chart pH in solution 14. The variations in the pH values can be attributed to the challenges in color interpretation when using the pH chart. Some of the resultant colors of solutions did not exactly match the color of the pH chart leading to the discrepancies in the pH values as the closest color was taken. The slight variations in the pH chart values and pH meter values can be attributed to the sensitivity of the pH meter that allows it to quantify small changes in pH between 0.1 and 0.9. The pH chart, conversely, does not allow for the determination of pH values smaller than one

The Creature in the book The Animalinside Essay Example | Topics and Well Written Essays - 750 words

The Creature in the book The Animalinside - Essay Example The combination of the images and the accompanying text take a reader through the experiences of the dog encountered. Since there is an outstanding harmony between the images and the text, the book stands on its own as an exemplary cultural event. The accompanying texts help the reader understand the journey undertaken by the dog as well as its future intentions when it is freed from the box. This paper will present a critical analysis of the meaning of the images in the book. The book titled The Animalinside comprises of 14 brief monologues accompanied by 14 outstanding images. A close analysis of the history of the book reveals that all the13 images are coming after the first one was painted in relevance to the first text. The first text came out as an inspiration of Neumann’s two-dimensional creature. The creature has features that make readers view it as a dog, although it tends to be in a leading position in a limited three-dimensional space. The creature highlighted in t he images does not qualify to be a human being. It has outstanding similarities to a dog but has not visible front legs (Ehrenreich 19). The texts accompanying the images reveal Krasznahorkai’s expertise in the use of language, which surpasses the normal skill of telling a story. The accompanying text is highly powerful and readers need to be keen to understand the meaning. After Neumann had produced his first image, Krasznahorkai developed the first accompanying text. In response, Neumann developed 13 more images that Krasznahorkai responded with accompanying the text. The book represents a multimedia collaboration combining expertise from art and literature. Krasznahorkai developed his text in prose form and focused on the creature depicted by Neumann (Pinker 187). The writer began by highlighting that the creature was willing to get out of the bondage in which he existed. Krasznahorkai helps the reader have a direct connection to the mind of the creature.
