What does (aq) mean?
« on: November 20, 2009, 10:30:59 AM »
Like in

Ba(s) + 2H2O(l) ---> Ba(OH)2(aq) + H2(g)

I realise that
s: solid
l: liquid
g: gas
but aq?

---

Also, when searching for the solution to one of these equations, what do I search for (in Google)?
Just Ba + H2O or what?

(aq) refers to "aqueous", which means: in water. In your case, you have Ba(OH)2 in solution in water http://en.wikipedia.org/wiki/Aqueous.


As for your search on Google, just try anything that works. Internet is a wild untamed land where order and rigorous classification do not apply. Wikipedia is usually a good start.
You can as well come again to this forum to discuss about anything: sports, gossips, hobbies, jokes,... You can even talk about chemistry here ;D

"Wikipedia is usually a good start."

However, I would always make sure that information from Wikipedia is verified elsewhere, any idiot can scew it up with a bit of malicious editing. Generally the science stuff is more immune than the pop culture references, but not totally.
Experience is something you don't get until just after you need it.
