## Homework Statement

He, I'm trying to do some geochemistry homework, and I need to plot something as Log ([x]/[y]) vs Log[z], in the equation I'm having trouble with there's no z though so I just need to find what log([x]/[y]) is.

## Homework Equations

My equation is 1/([Na]^2)*[H] = 10^109.4

## The Attempt at a Solution

Not much but I sort of worked to:

-2log[Na] = log[H]+109.4I I just can't get rid of the -2 though, away from the Na, and join the Na and H so that it's Na / H = ans

I tried the year 10 stuff, squaring both sides, and on and on..

I feel like I'm missing some mathamatic tool. Or maybe something simple

(Also I'm plotting log([Na+]/[H+]) vs log [H4SiO4]

I have lots of chemical equations to plot, though in this one there is no [H4SiO4], so I just need to find what log([Na+]/[H+]) is equal to and then plot that as a horizontal line.

So I just need to re-arange so I have (x/y = something) Then I can just take the log

For more background I'm constructing a mineral stability diagram.)
