200.00mL of 2.00 M solution of a weak acid is mixed with 300.00mL of a 2.00 M solution containing its conjugate base. 50.000 g ofthe slightly soluble salt silver acetate (AgC2H3O2) is added tothis buffer solution. After thorough mixing, the solution isassumed to be saturated. To determine the amount of the solid whichremains undissolved, the solution is filtered, and the residue iscollected and dried; the mass of the undissolved solid is 30.369g.
a)Based on this information, Calculate Ksp' for silver acetatein this buffer. (*Note Ksp PRIME is needed, not just regularKsp)
b)Using your value for Ksp', determine the pH of the buffersolution.
c)Based on the pH of the buffer solution, identify the weak acidused to produce it.

A general approach of this question The buffer will limit the available concentration of CH3COO the dissociation of CH3COOH is controlled by H in the buffer If CH3COO is consumed neutralized by the buffer you may expect a higher apparent solubilty of CH3COOAg See Answer
