There's 5 parts to the problem but it starts off "at 25^oC 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, k_b/k_a.  But what does it mean if its 4.1% ionized? how does that relate to the problem..

[Borek]

1% or 4.1%?

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

[Funk Master Widge]

yeah I meant 4.1%

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

[Borek]

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