150 mL of 0.15 M Na₂SO₄ is mixed with an equal volume of 0.050 M AgNO₃. Select all the options that correctly show the steps used to determine whether or not a precipitate will form if Ksp for Ag₂SO₄ = 1.5 í— 10-5.
1) Calculate the moles of Na₂SO₄ and AgNO₃
2) Calculate the molar solubility of Ag₂SO₄
3) Compare the molar solubility of Ag₂SO₄ with its Ksp
4) If the molar solubility is greater than Ksp, a precipitate will form
