QUESTION 18 Predict which of the following compounds is soluble in chloroform (CHCI3). a. Propane (CH3CH2CH3) O b. Toluene (C7H8) OG Carbon tetrachloride (CCI4) d. Acetic acid (CH3COOH) QUESTION 19 Will a precipitate form when 0.012 M Pb(NO3)2 and 0.020 M KCI are mixed at 298 K? PbCl2 (s) = Pb2+ (aq) + 2 Cl (aq) Ksp = 1.17 x 10-5 at 298 K O a. No, a precipitate will not form, because Q > Ksp. O b. Yes, a precipitate will form, because Q < Ksp: Ksp CE No, a precipitate will not form, because Q < O d. Yes, a precipitate will form, because Q > Ksp:
