Problem
When 35.0 mL of 0.200 M Pb(NO₃)₂ is mixed with 25.0 mL of 0.350 M KI, a yellow precipitate forms according to the net ionic equation
Pb²⁺(aq) + 2 I⁻(aq) → PbI₂(s)
After the reaction reaches completion and the precipitate is removed, what is the concentration of Pb²⁺ ions remaining in the 60.0 mL of solution?
(a) 0.0750 M
(b) 0.0438 M
(c) 0.0219 M
(d) 0.000 M
