The acid dissociation constant for HBro is 2.8 x 109 . Calculate the equilibrium concentrations of all substances if the initial concentration is 0.050 M for HBro. 2. A student prepared a 0.855 M solution of chloro acetic acid, CH2CICOOH, and measured the pH to be 1.48 at 25 C. Calculate the Ka for the acid. 3. What is the original molarity of an aqueous solution of CN whose ph is 9.13 at 25*C? Ko = 2.04 x 10-5 4. Calculate the pH of a 0.125 M solution of KN3 at 25*C.
