QUESTION 13 1 points Save Answer What is the solubility, in moles per liter, of BaSO4...
Calculate the solubility of barium sulfate. BaSO4 in units of grams per liter. Ksp (BaSO4) = 1.1x10-10 solubility = AL The equilibrium concentration of chloride ion in a saturated lead chloride solution is M. In the presence of excess OH, the Ar+ (aq) ion forms a hydroxide complex ion. Al(OH)4 Calculate the concentration of free Ap+ ion when 1.56x10-mol Al(CH2C00)3(s) is added to 1.00 L of solution in which [OH-] is held constant (buffered at pH 12.10). For Al(OH)4, Ke=...

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
