Solution: Will a precipitate form when 10 mL of 0.015 M [Hg +] and 10 ...

Question

Will a precipitate form when 10 mL of 0.015 M [Hg +] and 10 mL of 0.015 M [SO 2-] are mixed? 

Ksp of Hg2SO4 is 6.5 x 10 -7.

a. Yes; Q = 3.4 x 10 -6 which is larger than Ksp, a precipitate will form. 

b. No; Q = 3.4 x 10 -6 which is larger than Ksp, a precipitate will not form.

c. Yes, Q = 4.2 x 10 -7 which is smaller than Ksp, a precipitate will form. 

d. No; Q = 4.2 x 10 -7 which is smaller than Ksp, a precipitate will not form. 

e. No; Q = 3.4 x 10 -12 which is smaller than Ksp, a precipitate will not form.
