MOC0sn 8. Will KCI04 precipitate when 20.0 mL of a 0.050 M K* solution is added...
Will KClO4 precipitate when 20mL of a 0.050-M solution of K+ is added to 80mL of a 0.50-M solution of ClO4−? (Hint: Use the dilution equation to calculate the concentrations of potassium and perchlorate ions in the mixture.)
Will a precipitate of BaSO_3 form if solution of 10 mL 0.050 M Ba(NO_3)_2 is added to 15 mL of a 0.020 M Na_2SO_3? (K_sp = 5.0 times 10^-10) A. Yes, because Q < K B. Yes, because Q > K C. No, because Q < K D. No, because Q > K
When 20.0 ml of a 0250 M (NHS solution is added to 1500 ml of a solution of CuNOJ, CuS preciptate forms The precipitate is then filtered from the solution, dried, and weighed If the recovered CuS is found to have a mass of 0.3491 g what was the concentration of copper lons in the original CuNO) solution? 333-102 M O 365 10 M O 243 102 M O 122 102 M O 487 102 M
Will lead chloride precipitate when 275 mL of 0.134 M solution of lead nitrate is added 125 mL of 0.033 M solution of sodium chloride? Ksp = 1.7 x 10^-2
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
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
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
Will a precipitate form when 100.0 mL of 6.8 x 10-4 M Mg(NO3)2 is added to 100.0 mL of 1.2 x 10-4 M NaOH? The ion product for Mg(OH)2 is 1. Since Q is than Ksp, Mg(OH)2 precipitate from the solution.
A solution is prepared by mixing 20.0 mL of 0.050 M acetic acid and 10.0 mL of 0.100 M HCl. What is the pH of the solution? ( Ka acetic acid = 1.8 x 10-5) A. 2.36 B. 0.22 C. 1.48 D. 1.00 E. 0.48
