Activity coefficient

[Neon]

Hello,

I would like to know if I also have to square the activity coefficient in addition to the equilibrium constant of silver, if I want to express the solubility or solubility product Ag₂SO₄ 📖.

\(Ksp = γ(Ag+)square *[Ag+]square *γ(SO₄₂')*[SO₄₂-]\)

or

\(Ksp = γ(Ag+)*[Ag+]square *γ(SO₄₂')*[SO₄₂-]\)

Thanks in advance!

ai = γ*ci

ai^2 =(γ*ci)^2 = γ^2*ci^2

Ksp=[Ag+] 2∗[SO₄ 2-]

Ksp=γ(Ag+)∗[Ag+]₂∗γ(SO₄ 2−)∗[SO₄ 2−]
