5. The molar solubility of Pb(IO3)2 in a 0.10 M NaIO3 solution is 2.4x10^-11 mol/L. What is Ksp for Pb(IO3)2?

Enter your answer in scientific notation

Explanation / Answer

Ammonium nitrate: NH4NO3 this is an acidic salt, because NH4+ is the conjugated acid of a weak base, NO3- is the conjugated base of a strong acid so it can
