. The Ksp of barium sulfate is 1.1 × 10–10. What is the sulfate-ion concentration of a 1.0-L saturated solution of BaSO4 to which 0.025 mol of Ba(NO3)2 is added? 4.4 × 10–9M 1.0 × 10–5M 6.6 × 10–5M 2.8 × 10–12M

Answer:

[tex][SO_4^{2-}]=4.4*10^{-9}M[/tex]

Explanation:

From the question we are told that:

[tex]Ksp=1.1*10^{-10}[/tex]

Volume of [tex]SO_4^{2-}=1.O[/tex]

Moles of  [tex]Ba(NO_3)^2 =0.025[/tex]

Generally the equation for Ksp is mathematically given by

[tex]Ksp=[Ba^{2+}][SO_4^{2-}][/tex]

[tex]1.1*10^{-10}=[0.025][SO_4^{2-}][/tex]

Therefore

[tex][SO_4^{2-}]=4.4*10^{-9}M[/tex]
