150.0 mL of a 0.200 M solution of KIO3 is added to 11.4 mL of 0.100 M La(NO3)3. Compute the equilibrium concentration of La3+ in the resulting solution. Ignore activity coefficients. Ksp = 1.0 x 10-11 use the below equation to find the net ionic equation.
KIO3(aq) + La(NO3)3(aq) ---> La(IO3)3(s) + KNO3(aq)
