pH, Ionization Problem
« on: February 08, 2009, 05:23:54 PM »
There's 5 parts to the problem but it starts off "at 25oC a 0.0100M ammonia solution is a 1% ionized.  Calculate (a) the concentration of the OH- and NH4+ ions..."

We learned how to find pH, pOH, the concentrations of H and OH, kb/ka.  But what does it mean if its 4.1% ionized? how does that relate to the problem..

1% or 4.1%?

Of the initial ammonia amount x% was converted to ionized form.

yeah I meant 4.1%

so does that just mean that we are dealing with 4.1% of the .01M solution in any case?

Not sure what you mean by "any", could be it is overgeneralization.
