For a solution in which ionic strength is 0.05 calculate K'sp for

(a) AgSCN

i tried using these equations but i can't figure it out and i have test in 3 hours

ionic strength = 1/2([A]Za^2+[B]Zb^2)

aaronq · Answer

$$A _{x}=\gamma _{x}[X]$$


where Ax is the activity and gamma is the activity coefficient

aaronq · Answer

also $$-\log \gamma _{x}= 0.51Z _{x}^2\sqrt{\mu} $$
