⑷ 用英语写一封信关于化学学习生活
Hello XXX,
I am writing to let you know something about my study in chemistry.
It is really fascinating to see chemical experiments. For instance, we followed our teacher's demonstration for the neutralization of an acid and a base. A few drops of phenolphthalein is added into 2N HCl solution in a flask which gives pink color, When a 2N NaOH solution is slowly added in to the flask. The pink color changes instantly into colorless at certain stage. It is a neutral point, indicating pH value reaches to 7.
All of my chemical knowlages come from the Peorid Table. I learnt from it what atom is, what element is.
But chemistry is a quite complex science. I must study hard to understand.
Best wishes,
XXX
