Chemistry 2080 Spring 2011 Problem Set #9 - due date: Friday April 22rd at 2 pm Name:________________ Lab TA Name:__________________ Lab Day/Time:______________________ 1) Suppose that 50.0 mL of a 0.0500 M solution of Pb(NO 3 ) 2 is mixed with 40.0 mL of a 0.200 M solution of NaIO 3 at 25°C. Calculate the [Pb 2+ ] and [IO 3 ] when the mixture comes to equilibrium. At this temperature, K

Unformatted text preview: sp for Pb(IO 3 ) 2 is 2.6x10-13 . 2) Compare the molar solubility of AgOH in pure water, with that in a solution buffered at pH 7.00. Note the difference between the two cases: when AgOH is dissolved in pure water, the pH does not remain at 7. The value of K sp for AgOH is 1.5x10-8 at 25°C....
