Question

1 A.What is the Q value when 275.0 mL of 0.020 M BaCl₂ and 225 mL of 0.040 M Na₂SO₄ are mixed together. The Ksp of BaSO4 is 1.5 x 10 ^–9

Note: Your answer is assumed to be reduced to the highest power possible.

1 B.Will a precipitate form when 275.0 mL of 0.020 M BaCl₂ and 225 mL of 0.040 M Na₂SO₄ are mixed together. The Ksp of BaSO₄ is 1.5 x 10 ^–9

^{yes or no}

1 C.A solution contains 4.25 x 10^–5 M Na₃PO₄. What is the minimum concentration of AgNO₃ that would cause the precipitation of solid Ag₃PO₄ (Ksp = 1.8 x 10 ^{–1 8})

Note: Your answer is assumed to be reduced to the highest power possible
