Chemistry MChem personal statement example

Why do you want to study this course or subject?

For six years I worked the mixing counter at a trade decorating merchant, and the question customers asked most often was why the deep red they had chosen could only be made in one particular tin. The answer lies in the base. Pastel bases are loaded with titanium dioxide to give opacity, while deep bases contain far less so that added colourant is not washed out. Explaining that again and again made me want to understand the chemistry properly rather than repeat what the training sheet said. Why does titanium dioxide scatter light so effectively? Why does an acrylic emulsion dry as its water evaporates and the polymer particles fuse, while an alkyd gloss keeps hardening for days as it reacts with oxygen? Those questions led me back to education at twenty-eight. I want to study chemistry at MChem level because I enjoy the parts that need sustained effort, such as following a mechanism step by step or seeing why a calculation predicts what happens at the bench. An integrated master's would give me time to move from the foundations to an extended research project. I am drawn to materials and polymer chemistry, though I expect my interests to widen as I meet areas I have only read about.

How have your qualifications and studies helped you to prepare?

I am completing an Access to HE Diploma in Science at my local college, studying chemistry, biology and mathematics units alongside part-time work. So far I have achieved distinctions in all my assessed chemistry units. Practical work has been the biggest change from my old job. Instead of following a formula for a tint, I have had to plan procedures, record uncertainties and explain anomalies. In one assignment I used colorimetry to find the concentration of copper(II) sulfate solutions from a calibration curve. My results followed the expected Beer-Lambert relationship closely, and I wrote up why the most concentrated solution began to drift from the line. Titrations taught me a patience with a burette that I lacked at first. Mathematics was the area I felt least confident in, so I worked through logarithms and rearranging equations with extra online exercises until pH calculations felt routine. Outside the syllabus I have read Why Chemical Reactions Happen by Keeler and Wothers, which made bonding and orbital ideas clearer than my textbook did. I also read Primo Levi's The Periodic Table, whose chapters drawing on his years in a paint and varnish factory struck a chord. I keep a notebook of questions I cannot yet answer, and returning to it shows me how much I have learned in a year.

What else have you done to prepare outside of education, and why are these experiences useful?

Working at the counter taught me accuracy under pressure. Colourant is dispensed in tiny measured amounts, and a mistake on a twenty-litre order costs both the customer and the branch, so I learned to check details calmly. I also trained newer staff on the tinting machine, which tested whether I really understood the process. I now work three evenings a week in the same branch to support my studies, so I am used to planning my time carefully. At home I keep a planted freshwater aquarium. When I set it up, I learned the nitrogen cycle the slow way. I tested ammonia, nitrite and nitrate with reagent kits every few days for weeks before adding fish, and I still log the readings. Not everything I do connects to chemistry. I play five-a-side football on Sunday mornings. Two afternoons a week I collect my nephew from primary school and help with his reading, which has made me better at slowing down and listening. Returning to study has meant giving up free time and a steady full wage, and I have made that choice deliberately. I am ready for the workload of a four-year master's degree, and I bring the reliability and practical sense that my years of work have given me.
