Plot an implicit function

I'm trying to plot the general solution for titrating an n-protic acid with an m-protic acid base. The solution cannot be expressed explicitly.

I've poked around in here and the manual but can find anything that really addresses the problem. I tried to find a way to make my function fill in a table and plot the table, but I can't get it to do even that.

File attaches as MathCad 14.0 file.

TIA.

I think your brackets confused Mathcad for some reason! Remove them and you get an explicit solution - see attached.

Why are you trying to solve it symbolically?

Because I'm not familiar with MathCad and am curious to see how it works. And I wanted an explicit function because that would've been MUCH easier to work with.

I'll be cat-haired. Sho' nuff.

Take the brackets away, and MathCad can find an explicit solution.

I wish I knew how I managed to confuse MathCad. I bet it thought the Kw/[H] was part of the summation somehow.

I now have a general solution. Life is good.
