1) Calculate the pH at the equivalence point in titrating 0.10 M solution of HBR with 0.08 M NaOH
I know how to do the problem if volume amounts are included. I don't know how many liters are used and consequently the number of moles. Should I just invent some volume for one and calculate the pH based on how much the other takes to titrate it?
2)I need to calculate the equilibrium constant for
Ag2S + 4CL + 2H <---> 2AgCl2 + H2S
The only information provided is Kf (what the heck is Kf?) is 1.1x10^5 for AgCl2
How does one proceed? Thanks! :)
