胞磷胆碱钠2005版鉴别的翻译:
原文
(1）取本品约10mg，加无水乙醇1ml使溶解，加碘化钾试液2ml与稀硫酸4ml，摇匀，加淀粉指
示液数滴，溶液即显蓝紫色。
（2）取本品的氯仿溶液（1→10）3～4滴，待氯仿挥发后，加2％香草醛硫酸溶液1滴，即显红色，放置，渐
变棕色。
（3）取本品，精密称定，加氯仿制成每1ml中含20mg的溶液，依法测定旋光度（附录Ⅵ E），应显右旋光性。
翻译如下:
1.Transfer the sample about 10mg , dissolve in anhydrous alcohol 1ml, then add potassium iodide solution 2ml and dilute sulfuric acid 4ml ,and mix , add the starch indicator several drops, the color of solution is Blue purple
2. Transfer the sample of chloroform solution 3 to 4 drops, after chloroform to be volatile, add 2% Vaniilin sulfate Solution 1 drop. The color of solution is red, place the solution, the color gradual change palm.
3. Transfer the sample, accurately weighted. Add chloroform to make the solution about 20mg per ml, according to CP 2005, determinate the rotation. It should show right optical rotation.

传真给你了，不知你收到没有？
shake是晃动，stir是搅动，这里要看实验的实际做法是怎么样的了
我觉得在这里面也能看出些我们跟老外思维的不同

用"a couple of drops"也可以

I think, shake是振摇(用手晃动即可），stir是搅拌（需要玻棒或搅拌子）。

溶液显**色一般说成a ** color is produced.

学习了
I have been reminded many times that “never” say red color, blue color etc. as they are Chinglish (i.e. it should be green grass, not green color grass). However, happyjyl is expert in this field, I therefore believe that “溶液显**色一般说成a ** color is produced” is a typical expression in chemical testing. (I also search “a red color is produced” in google, and found 4120 results)
“Never” is not absolute.
On the other hand, there may be an alternative for 加淀粉指示液数滴，溶液即显蓝紫色:
add a few drops of starch, then the solution will become indigo blue.
(here I remove the word “color” from “indigo blue color” suggested by littlewing at 3/F)
