Question

What is the pH of a 10^-4 mol/L concentration of NaOCl added to a 0.1M solution of NaCl at 35^°C.

RXNs:

HOCl <-> H⁺ + OCl^- K_a = 10^-7.5 ΔH° = 5.95 kcal

H₂O <-> H⁺ + OH^-

Please show

-Van’t Hoff equation to adjust K_a and K_w to 35^°C

-Please show adjustment of equilibrium K’s for ionic strength
