WHAT IS THE PH OF 0.50 M HC10? KA OF HC10 IS 3.5X10-8
That can't be HC10. It must be hypochlorous acid.
..............HClO ==> H^+ + ClO^-
I.............0.50......0......0
C..............-x.......x.......x
E............0.50-x.....x.......x
Substitute into the Ka expression for HClO and solve for x = (H^+) and convert to pH.
