Calculate the [OCl-] of a 7.03×10-2 M solution of the weak acid HClO (make an approximate calculation assuming that initial concentration is equal to the equilibrium concentration). Round your answer to 3 significant digits.
HClO = OCl- + H+
.....HOCl ==> H^+ + OCl^-
I...7.2E-2....0.....0
C....-x.......x.....x
E..7.2E-2 -x..x......x
Ka = (H^+)(OCl^-)/(HClO)
Substitute and solve for x
