For the laymen who aren't afraid of a very small amount of math, the reason pH can be negative is because the term pH is essentially shorthand for - log(x) where the x is the concentration of H⁺ in solution. If the concentration is super, duper high, this can drive pH to negative values.

Haha
Really nice !!! You are right, I should add this part which makes more sense ;)

我的妈呀，PH值是负数的酸.....不敢想象呀!

[mcw]

哈哈對啊
戴了兩層手套 XD

[tvb]

太可怕了,是不是肉沾上马上就化掉了呀,都来不及疼是不是

[mcw]

哈哈，不要想像就好了😂

I am sure you have to use a huge face mask before you can open this bottle up right? What are the uses of such an acidic acid?

[mcw]

Haha not really. I was working in a funehood and filiming this far from my operation haha
It actually rarely used alone in organic chemistry. We used to convert them to triflic anhydride and work with them, as they somehow resembles bromide/iodide properties ~

dunno why the first thing that pops up my mind is @acidyo , maybe was his gif banner XD

[mcw]

I recall he have a cartoon pouring some sort of chemicals out of a conical flask XD

爱吃醋的我看完心情有点复杂(´▽｀)
第一次知道原来胃酸的PH只有1，好强的酸呢，也难怪我胃溃疡发作的时候会那么疼…想想手上有创口再滴上醋……（我怎么就和醋过不去了😂）

[mcw]

哈哈其實你的胃黏膜能保護你的胃壁，由此你才不會受傷(回想如果你試過有胃酸湧上食道是多麼疼的)，只是胃潰瘍的時候沒有東西保護胃壁，還要發炎
所以呢，吃醋當然不會有事啦，醋比胃酸要弱上千倍呢

[nostalgic1212]

哈哈哈哈，吃醋只是个梗啦😂
我的胃算是千疮百孔了，一阵子好一阵子发作。不过以前很爱喝酒和吃冰饮，现在是万万不敢了

[mcw]

好慘啊🙈

[nostalgic1212]

不过没事啦，那么多年下来，我也学会如何和我脆弱的胃部“友好相处”了呢😊

要腐蝕到金屬既酸，係幾多pH？(諗起以前睇既電影，強酸液體腐蝕人。。。)

[mcw]

哈哈其實普通弱酸也可以溶到的，只是比較慢
其實胃酸應該都會溶得挺快的xdd
所以身體的保護機制起身很厲害的

[irenett]

Omg，咁胃酸真係好勁

[mcw]

胃壁更厲害xdddd

[lydiachan]

酸葡萄心理! XD

The most superior acid to all other Lewis and Brønsted acids tested.
useful post, thank you for the informations but i wish the post was longer to give more informations about this acid and its uses.

[mcw]

There are actually still more even stronger super acid. As a post for layman, I just try to make it not too long, but that is a good suggestion.
In particular, the acid alone dont have much application in organic chemistry. We used to prepare triflic anhydride from that and use it for synthesis. Triflate group is so interesting that it somewhat resembles bromide/iodide, which makes it relevant to us~

Nice post beautiful

[mcw]

Thanks ~
