I am trying to figure out an overall reaction constant, but I am getting stuck on the math behind the problem. I am at this point in the problem:(adsbygoogle = window.adsbygoogle || []).push({});

[Co(H2O)6] = [Co] x (k[H+]/(1+k[H+]))

And I am trying to mathematically get to

[Co(H2O)6] = [Co] x (1-(1/(1+[H+]k)))

When you ignore the chemistry, the equation is the same as:

a = b x (cd/(1+cd))

going to

a = b x (1-(1/(1+cd)))

How do you factor out the cd from the numerator?

Thanks!
