Oral presentation (See Oral Presentation Guidelines (pdf) )
I was fascinated by an experiment we recently did on using an acid to plate copper on a nail. I wanted to explore the topic further, which why I chose to study how the pH of an acid affects copper plating. After some research, I guessed that the lower the pH the more copper would be deposited on the nail. For my experiment, I made several different solutions of acid with pH’s ranging from 1 to 7. Then, I placed the pennies in each jar overnight. After that, I took out the penny and replaced it with the nail in each jar and observed what happened over three days. The nail in the solution with a pH of 1 was completely dissolved. The nail in the solution with a pH of 2 was partially dissolved. The nail in the solution with a pH of 3 had a fair amount of copper plated on it. The nail in the solution with a pH of 5 had a bit of copper. The nail in the solution with a pH of 7 was unaffected. I learned that the pH of the acid solution is important to copper plating, but unlike my hypothesis, it needs to be around pH of 3 to be the most effective.
Abstracts are powerful 'short stories' that are used in journal articles and conference presentations. An abstract will help reviewers to decide whether to accept your paper, conference abstract or grant application, and help readers to decide whether to read your paper or attend your presentation. Often people will read only the abstract of a paper (even if they cite it), so it is crucial that your abstract gets your message across. Thus, when it comes to writing abstracts, it is worth the effort to do this well. This Getting Started Guide provides tips and information to assist you with this exercise.
