7. A 25.0 mL solution of 0.0015M BaCl2 is added to 20.0 mLs of 0.0010 M Na2SO4. Determine if the resulting solution will have a precipitate form or if it will remain unsaturated. Ksp (BaSO4) = 1.1.x 10-10
If 100 mL of a .100 mol/L CaCl2(aq) and 100 mL of 0.0400 mol/L Na2SO4(aq) are mixed at 20°C, determine whether a precipitate will form. For CaSO4(aq) at 20°C, Ksp is 3.6 x 10-5.
Question 1 1 pts The Ksp value for BaSO4 Ksp = 1.1 x 10 10. If 50.0 mL of 2.0 x 10-4 M Ba(NO3)2 is mixed with 350.0 mL of 1.0 x 10-5 M Na2SO4, will a precipitate be observed? A precipitate forms because the ion pair product, Q> Ksp A precipitate forms because the ion pair product, Q< Ksp. No precipitate forms because the ion pair product, Q = Ksp No precipitate forms because the ion pair product, Q<Ksp...

QUESTION 18 1 points Save Answer Will a precipitate form when 20.0 mL of 1.8 x 10-3 M Pb(NO3)2 is added to 30.0 mL of 5.0 x 10-4 M Na2SO4? The Ksp of (PbSO4) is 6.3 x 10-7. OA. yes, because the ion product > Ksp OB. no, because the ion product< OC.no, because the ion product > Ksp OD. 'yes, because the ion product < Ksp Ksp ОЕ. no, because Ksp is less than the ion product
23. Will a precipitate form when 100. mL of 8.0x 103 M Pb(NO3)2 is added to 400. mL of 5.0 x 10-3 M Na2SO4? The Ksp of PbSO4 is 6.3 x 10-7 A. No precipitate forms because Qsp Ksp B. Yes, a precipitate forms because Qsp>Ksp C. No precipitate forms because Qsp> Ksp es, a precipitate forms because Qsp Ksp
