Will a ppt of SrF2 (s) form if you mix 7.7 x 10-4 M Sr(NO3)2 (aq) with 3.8 x 10-5 M NaF (aq)? (Which of the following is entirely correct?) OQ = 2.9 x 10-8 ppt forms O Q = 2.9 x 10-8, no ppt Q = 1.1 x 10-12, ppt forms O Q - 1.1 x 10-12, no ppt O Q = 4.4 x 10-12, no ppt
Suppose 50mL of 8.4x10-7 M Pb(NO3)2 (aq) is mixed with 200mL of 9.7x10-4 M Na2CO3(aq). Calculate Q and determine whether a ppt of PbCO3(s) will form. (In other words which of the following is entirely correct?) (Suggestion: Write the dissolving equation and Ksp expression for PbCO3 before starting this problem). a. Q=8.1x10-10 , no ppt b. Q=8.1x10-10 , ppt forms c. Q=1.3x10-10 , no ppt d. Q=1.3x10-10 , ppt forms e. Q=2.5x10-9 , ppt forms
