(6) Let's see how the spectator" ions present in solution affect the pH of a weak acid (a) What is the pH of a 0.0200 M benzoic acid (Ka = 6.28 x 10) solution in water? (b) What is the % dissociation of the benzoic acid in pure water? Now we'll add some "spectator" ions to the solution. If the benzoic acid is dissolved in 0.10 M CaCl2 instead of pure water: (c) Calculate the ionic strength of the solution...

1) The equilibrium concentration of sulfate ion
in a saturated silver sulfate solution is __
M.
2) I need an actual numerical value for K.
I just need the correct answers. I will rate.
there's no data. this is exactly how the problem is
presented on cengage and it can be solved this way.
