when 10.0 ml of .012 M PbNO32 is mixed with 10.0 ml of .030 M KI, a yellow precipitate of PbI2 forms.
calculate the initial molarity of Pb+2
calculate the initial molarity of I-
On measuring the equilibrium concentration of I-, it came out to be 8.0 x 10^-3 M. Calculate the molarity of I- precipitated.
