Lab Report Acid Base Titration Essay Example

Lab Report Acid Base Titration Paper This allows for quantitative analysis of the concentration of an unknown acid or base solution. It makes use of the naturalization reaction that occurs between acids and bases and the knowledge of how acids and bases will react if their formulas are known. Acid-base titration can also be used to find percent purity of chemicals. When a weak acid reacts with a weak base, the equivalence point solution will be basic if the base is stronger and acidic if the acid is stronger. If both are of equal strength, then the equivalence pH will be neutral. However, weak acids are not often titrated against weak bases because he color change shown with the indicator is often quick, and therefore very difficult for the observer to see the change of color. The point at which the indicator changes color is called the end point. A suitable indicator should be chosen, preferably one that will experience a change in color (an end point) close to the equivalence point of the reaction. First, the burette should be rinsed with the standard solution, the pipette with the unknown solution, and the conical flask with distilled water. Secondly, a known volume of the unknown concentration solution should be taken with the pipette and placed into the Monica flask, along with a small amount of the indicator chosen. The known solution should then be allowed out of the burette, into the conical flask. At this stage we want a rough estimate of the amount of this solution it took to neutralize the unknown solution. The solution should be let out of the burette until the indicator changes color and the value on the burette should be recorded.

At least three more titration should be performed, this time more accurately, taking into account roughly where the end point will occur. The initial ND final readings on the burette (prior to starting the titration and at the end point, respectively) should be recorded. Subtracting the initial volume from the final volume will yield the amount of iterant used to reach the endpoint. The end point is reached when the indicator just changes color permanently.

Sample of GED Essay

Sample of GED EssayA sample of the GED essay is a written work by students of General Education (GED) requirements. It is the core work of this program and is what a student must do before he or she can advance to the next level. The sample is required because it is used as a basis of the actual GED essay, which contains content that will be tested.The standard way of writing an essay for GED is through the use of words and phrases that would be difficult for a common person to understand. Thus, it is usually quite detailed and requires a certain amount of knowledge on certain subjects. By doing this, the student will have to come up with a long but simple question and answer that will be used as a basis for the actual essay. In order to pass the exam, the student must write a sample essay of this kind, a test that is especially designed to expose weaknesses in the students' knowledge.Students must realize that the writing sample is not an actual essay they are going to read on the e xam. The writers who compose these works are college teachers who have been instructed by the Educational Testing Service (ETS) to write such a sample. They are instructed to take into account all the subjects covered in the course and to compose the entire composition in a way that it can be used as a basis for the essay. This makes the students understand that their essays will be put to the test and that they will have to write something that is worth getting good marks in.If you want to have a better idea of how the writers choose the topic for the sample, then you should be aware that there are several criteria that they will use. These include the year in which the program was conducted, the subject that are normally taught in the course, and the grade of the students who took the program. The latter will determine the content that is included in the essay.Most often, the writers use a study abroad program as a basis for the sample. This is because most students who are attend ing universities or schools in other countries have a better chance of understanding and applying what is being taught at their school. Moreover, people who study abroad have an advantage when it comes to learning about things they will need to know if they want to get a job in the United States. As long as they pass the test, they will have the chance to work and to live in the US, especially after they graduate from their studies abroad.The writers also take into account the subject in which the students study and how it is taught in the classroom. For example, some students might be told that music is the main subject of the class, while others might be told that literature is the one taught. In addition, students are also sometimes taught the composition part of the course, even though it is not the main subject of the course.Another thing that they will consider is the type of student in a class, because a different subject might not be well-suited for one student. Other studen ts may not be able to understand how music or literature are being taught in a specific class. However, they must keep in mind that there is no rule that says that if a certain subject is taught in a certain class, then the students can only learn about it when they take the GED test.While the writers and the students involved in composing the sample of GED are very particular about the topics they will use for the examination, there are some topics that are usually included. These are those subjects that are normally taught in the course, but not taught in the class itself. For example, geography will be included in the essays, as will political science and psychology.
