For this, you need to understand what pH is -log[H+] 

neutral solution of water means that the concentration of H+ equals the concentration of oH- 

Usually at 25 degrees celsius 

$$Kw = [H^+][OH^-] = 1*10^-14 $$

As i said if the solution is neutral [H] = [OH-] and for this to be the case their product has to equal so what do you think it might be?

i honestly have no idea

photon336 · Answer

well for the concentrations to be equal they both have to be {10^-7] 

because 

[10^-7][10^-7] = 10^-14
