Concentrated acids? Extremely strong oxidizing agents? Carcinogens? Stuff that intercalates with DNA? Mildly pathogenic bugs? Random sharps?
I respect all those things. But the lab activity that still makes me anxious is whenever we have to move the gas cylinders.

Nice post, argon is also very usefull on any spectroscopy where you need to use an ICP and sometimes even on gas cromatografy .

Oh that's right! I rarely use ICP and almost forgot that!!!

Yes, chain them to the wall!
These bottles have been known to propel themselves through concrete block walls.
I didn't know argon was above CO2 in atmospheric gases, but hey, after Nitrogen and Oxygen, everything is a mere fraction of a percent.

Well, on the TV show mythbusters they made that experiment, I don't remember what kind of gas they used (probably just air) or what pressure but it went trought a concret wall easy, it probably could be an interesting experience in a lab haha.

感覺放在瓶子裡的氣體都要很小心啊~~~ XD

對啊,還有如果一下子釋放全部氣體出來會把氧氣排走讓人窒息的!!

天哪,氬氣居然比二氧化碳釋放還多,這個真是很意外。還好氬氣不會污染環境。

氯化鉀(為高血壓病人而設的鹽)這不會吃成甲亢嗎,我怎麼這麼多問題。。。哈 哈

其實食鹽真的沒太多碘,吃到高血壓都不夠補充碘質,所以呢,這個不用擔心 XD
(而且很多時候氯化鉀都是礦物岩鹽來,不是來自海水,應該沒有太多碘的)

哦哦原來是這樣,我其實有段時間總吃海帶,想多補點碘,感覺能提高新陳代謝哈哈

紫菜都是海帶嘛...... 吃起來吸引一點嘛XD

现在好你我们都不太缺碘了,以前好多人缺碘,都在食里加碘。现在人都营养过剩了哈哈
