Title: PH at standard condition
Post by: stevenAitsover on April 16, 2008, 11:16:05 AM

What would be the PH of the solution at standard conditions? (HINT: What are the concentrations of all aqueous species at standard conditions?) Plz help

3Co(s)+2NO3-+8H+(aq)-----> 3Co+2(aq) + 2NO(g) +4 H20(l)

pH of reaction mixture will depend on the amount of acid used in this reaction.
You still have to be more precise. May be you are asking about pH of Co(NO3)2 solution?

Furthermore, "standard conditions" isn't as well defined as you'd think.  If they mean "standard conditions for temperature and pressure", we can look it up, but you don't seem to be using any gas, so we wouldn't even need it.  We're going to need the entire question, carefully written out, to see what level of difficulty your class is at, to give useful help.
