## aaronq 2 years ago 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)

1. aaronq

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

2. aaronq

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