i know that's what the pH is.. but i need more detail about this equation?

This is simply the graph that models pH,
the "log" function is the inverse of an exponential function. The [H+] which is also known as [H3O+] stands for the concentration of hydronium; the acidic compound of all acids. Thus we are saying the negative log of the concentration of H+ ions or hydronium is equal to the pH.
When given the pH you can use this equation to calculate the concentration of H+ ions and visa versa
alternatively we have the pOH which equation states that pOH= -log[OH] this is the same thing yet measuring the basic component (pH+pOH=14)
hope this helped

It is just a way of converting the concentration of H+ ions into a pH
e.g. If the concentration of H+ ions was 1.0 x 10^7, then finding the negative log of that would give a pH of 7.
