Title: A very noob question
Post by: luffy on June 12, 2011, 10:53:40 pm
Hey guys:

I just thought of a very simple question, but I can't seem to find a definite solution. Haha.

The question is, what happens when you react Water (i.e. H2O) with Na2CO3?

If someone could tell me the products/equation, it would be very much appreciated.

Thanks for your help.

Sodium carbonate is a base, so I would assume it's simply acid base in water, where water acts as an acid (water is amphiprotic)

Na2CO3 is a strong base, hence water acts as an acid

Na2CO3 + H2O -> Na2HCO3+ + OH-

Hopefully I'm not mistaken :P

Would the hydroxide ions be in the form of sodium hydroxide? not implying this is right, just thought of it then

Ah - thanks. I had a feeling it would be this simple, but I wasn't sure.

I appreciate it.

ummmmm, it could be hahaha

this is not something i want to worry about just before the exam! hahahahahhahahahahaaha
its probably not relevant to the exam though, its a pretty silly reaction...

Yeah nah you may be right, base + acid -> salt + water

thanks, so the ions are dissociated in water :)

It's an Acid + Metal Carbonate Reaction:

2H2O + Na2CO3 ---- 2NaOH + H2O + CO2

Or not as i read the previous post.....
