In a laboratory experiment, air containing $0\mathrm{.}50{10}^{-6}$atmHOCl is bubbled through deionized water $($initial $pH=7).$ What is the $pH$ of the water when the system has reached equilibrium? Note: You must use the methods presented in class $($this means an ICE table!$)$ to get full credit for this problem.

$HOClharr{H}^{+}+OC{l}^{-}(unbalanced)$

$p{K}_a=7\mathrm{.}54$

$K_H=6,500mo\frac{l}{L}*atm$
