Can someone explain how to solve the following problem? I am confused about how to answer this question without being given the value of K.
Find the initial concentration of the weak acid or base in each of the following aqueous solutions: (a) a solution of HClO with pH = 4.60; (b) a solution of hydrazine, NH2NH2, with pH = 10.20.

Re: Textbook Question #6D.7
The values of K are found in pg. 461, section 6C! You just find the concentrations for H+/OH- and substitute it into the equation for the equilibrium constant K and solve for the initial concentration. Hope this helps!
