Hi, I am Rajasekhar from India. could u please guide me to learn about the "powder/paste that melts the rocks/stones which said to have been invented by south asia/china/japan widely uses particularily in mines and quarees in order to melt the stones/rocks instead of blasting and explosions. waiting for ur reply. Thank You.

N.B: Please mail me to ""

query about some chemicals[edit]


1.Nitrocloric Acid

2.Cercloric Acid

3.Thoric Acid

4.China Paste otherwise called rock melting paste said to have been invented by chinese

 to melt the rocks/stones at mines or quareese.

                                              Thank You

Nitrochloric acid[edit]

I've never heard of nitrochloric acid, but perhaps you are looking for aqua regia, which contains both nitric acid and hydrochloric acid. It is one of the few acids able to dissolve gold.

Carboxylic acid = strong acid?[edit]

I'm not quite sure carboxylic acids are all strong acids. I'd think of them as weak acids, with the conjugate salts being relatively strong bases. --Rifleman 82 02:14, 28 March 2007 (UTC)


Doesn't miscible imply insoluble? Yet "insoluble" appears in contrast to it. Unfree (talk) 03:48, 12 December 2009 (UTC)

No, miscible implies soluble. --Cubbi (talk) 02:59, 13 December 2009 (UTC)

Hardware store[edit]

Crystalline oxalic acid is sold in hardware stores for bleaching wood and cleaning marble. Unfree (talk) 03:54, 12 December 2009 (UTC)

Hydrocarbons are acids[edit]

The article should say that all hydrocarbons are organic acids, since they can all dissociate into carbanions and H+. Whoop whoop pull up Bitching Betty | Averted crashes 02:16, 10 January 2012 (UTC)

That's would be a misleading statement, even though it contains a grain of truth. Most hydrocarbons are not very acidic. They don't neutralise most bases. We could go into a long discussion about how easily various hydrocarbons can be deprotonated and so on, but it would be a distraction. Almost any molecule can be depronated (given a strong enough base like BuLi) but we only call them acids if they are deprotonated fairly easily by normal-strength bases like NaOH. If you mix acetic acid and sodium hydroxide, a salt forms, sodium acetate. If you mix hexane with NaOH, nothing happens. That's why we say acetic acid is an acid but hexane isn't. --Ben (talk) 13:31, 10 January 2012 (UTC)
By that definition acetylene would be considered an acid, as it forms acetylides. Whoop whoop pull up Bitching Betty | Averted crashes 17:40, 20 February 2012 (UTC)
Again, acetylene is not what we'd normally refer to as an acid, because it takes very strong bases like BuLi to deprotonate it. The pKa of alkynes is about 25, compared to 16 or so for alcohols, 14 for water, 10 for phenols, 5 for carboxylic acids and about 0 for mineral acids like HCl. This means an alkyne is about a billion times less acidic than an alcohol, which itself is not very acidic (ethanol, for example, is not going to burn a hole in your trousers, whereas HCl will). Acetylene is much more acidic than alkanes, but much less acidic than proper acids. That's why we don't call it an acid - it only donates protons to über powerful bases. --Ben (talk) 20:00, 20 February 2012 (UTC)
Meldrum's acid? Whoop whoop pull up Bitching Betty | Averted crashes 04:21, 22 February 2012 (UTC)
As you can clearly see by reading that page, the structure was originally thought to be a carboxylic acid. As you can clearly see by reading that page, the is is as acidic as carboxylic acids, not a normal hydrocarbon. DMacks (talk) 04:36, 22 February 2012 (UTC)
