What am I required to do in this assignment?
- ⢠This referral requires you to produce a report that addresses each of the tasks given below (using complete sentences and paragraphs, and with appropriate in-text citation).
- ⢠These tasks guide you through the expected understanding of the science related to the buffer capacity practical that was supposed to carried out in this unit and identify aspects that should have been included in the practical report.
What do I need to do to pass? (Threshold Expectations from UIF)
- ⢠Accurately relate laboratory findings to the underpinning theory.
- ⢠Appropriately analyse and clearly present laboratory data obtained from the practicals.
- ⢠Produce a scientific report according to expectations described in the assignment brief.
How do I produce high quality work that merits a good grade?
Your report must address each of the takes below. The response to each task should be numbered appropriately. Submitted text must be in the form of appropriately constructed sentences and paragraphs. Single word answer or bullet point statements are not sufficient. Clarity of English language and presentation is essential throughout. Your ability to follow the instructions within this assignment brief is also essential. These are basic professional skills expected by all employers. Any figures must be numbered (e.g. Figure 1) and include a figure legend (located below the figure) that describes the content of the figure, provides the reference source (if you obtained the figure from elsewhere), and defines any abbreviations or symbols in the figure. Figures include any visual element such as diagrams, photographs, graphs, etc. Any tables must also be

numbered (e.g. Table 1) and include a brief title only (located above the table). Any abbreviations or symbols in the table should be defined in a footnote below the table. Your main written text must refer to the figure or table (e.g. see Figure 5) to show how the figure/table supports your writing and do so before the figure or table is displayed. Do not include figures or tables that are not referred to in the main text. Do not include excessive diagrams in your introductory material. Do not allow tables or figures to go over the page â this looks very messy and unprofessional.
All text must be written in your own words. Copying text from reference sources, friends or lab partners is PLAGIARISM. Copying text from somewhere else and then changing a few words in it here and there is also PLAGIARISM. You must read and understand your reference source, then explain your understanding in your own unique words, and then provide a citation â e.g. (Patel, 2014) â immediately afterwards to show where the information you have explained came from. Failure to do this is an academic offence and will be treated in accordance with the University regulations for plagiarism.
Your report must be divided into the following sections:
1.Present equations that define: (a) the pH of a solution; and (b) the generic meaning of p (as in pH).
2.Discuss the concept of dissociation of weak acids; present the equations that define the acid dissociation constant (Ka) and the pKa.
3. Explain the essential chemical components for preparing a pH buffered solution.
4. Explain the generic principles of acid-base titration.
5. Explain the concept of buffer capacity and present the equation that defines the quantitative measure Ã.
6. Explain why buffer solutions exhibit maximum buffering capacity at a particular pH.
7. Identify the dominant buffering components of phosphate buffer (pH 7) and report the applicable pKa value at that pH.
8. Discuss the autoionization of water, the relationship pH + pOH = 14, and report the concentration of the hydroxide ion (OH- ) in water at 25 °C.
9. Explain the meaning of the expression âstrong baseâ.
10.Using the example data in the table below, plot the buffer capacity estimates in a single
scatter plot (buffer capacity on the vertical axis, measured pH on the horizontal axis).Copy and paste the plot into your report. Give the figure: a figure number; a short descriptive title; and the minimum necessary information. Precede the figure with text that describes the important features of the buffer capacity curves and refers to the scatter plot by citing the figure number.
11.Interpret the meaning of the buffer capacity curves presented â particularly based on the underpinning theory (questions 6, 7 and 8).
References: You should include at least one peer-reviewed scientific journal article and at least one textbook as sources. These should be listed in correct UoB Harvard format in a single reference list. The reference list should only contain sources that have been cited appropriately – e.g. (Smith, 2010) – in the main text of your report. The University of Bedford Harvard referencing style should be used for citations:
