化学实验! Chemistry experiment!

STPM sem 3 chem experiment の story~~~

那天我们终于要来动手进行这学年最后一项的化学实验啦!兴奋!
Finally that day we are going to finish our final chemistry experiment for this semester! Feeling exciting!
实验虽然有很多的步骤不过还是很有趣!
Although there are many steps in carrying out this experiment but it is a lot of fun!
1, 第一步当然就是按照指示去那足够分量的材料。
The first step of this experiment of course is to take the material and apparatus that needed according to the experiment report.
2, 按照指示把两个液体混合起来,然后泡进冰里让温度下降。(最好是0-5度)
Then follow the step to put the solution that already mix together into the ice bath to let the temperature drop. (More prefer to let it drop to 0-5 degree)
3, 接着还是按照步骤在温度适合的时候加入其他的材料,然后轻轻地摇晃液体。
The following step is still following the experiment report, that is add in the other solution when the temperature of the solution is suitable. Gently swirl the solution.
4,接着就是把他放置在一旁(大约5分钟)然后加入最后的材料。他会变成红色的液体。接着就准备过滤要用的材料了(读report上的步骤)。过滤的其他部分就看图吧。(备注: 把沉淀物从原本的液体里过滤出来后用指定的液体冲洗)
Later, leave it aside for about 5 minutes. Then add in the final solution into the previous solution, you will get something red and look a bit oilly. This is time for you to prepare the apparatus state on the experiment report that need to filter the solution with the precipitate form. After separate the solution and the precipitate, wash the precipitate with cold acetone water that state in the experiment report.
5, 烘干后就会得到橙色的粉末了。
After drying the precipitate, you will get orange powder.

以下是有关这个实验的一部分图。
