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
