作文：I enjoy thinking differently and originally. When my chemistry teacher assigned a planning lab that involves “create a buffer solution using chemical compounds of appropriate concentration and explain why H2O cannot resist changes in pH。” Instead of rushing into finding a suitable acid and salt to create the buffer as our teacher expected, I immersed myself into uating the question itself. I asked myself that if a water molecule, when dissolved in a liquid with lower pKa, donates H+ just like CH3COOH does in aqueous solution, why can’t water be used as a part of a buffer? I asked myself that if NaCH3COO can be used as the conjugate salt of in buffer solution, with the same logic why couldn’t NaOH be used as the conjugate salt for H2O? From here I was able to think further, and although I was faced with more problems as I continued, by solving them one by one through referring to the most basic definitions and principles of chemistry and the information on my AP chemistry books, I find myself closer and closer to my destiny。
A few days later, I wrote my planning lab with the research question “using H2O and NaOH of equal concentration dissolved in liquid NH3 to create a buffer solution”. After my teacher praised me for the originality and feasibility of my idea, I once again felt the thrill of achieving something I desired. (235)
