问题描述：
What is the pH of 7.51x10^-8 mol/L HCl(aq)?
Give your answer accurate to two decimal places.
Note:You are dealing with a very dilute solution of a very strong acid.Think carefully!One approach is to write down mass and charge balance equations and all relevant equilibrium constant expressions.(Hint:The relevant equilibrium is the self-ionization of water.)
