A student sets out to determine the Ksp of the sparingly soluble salt, M2X3. This salt dissociates into the ions M3+ (aq) and X2- (aq). A sample of a 0.00300M M(NO3)3 (aq) solution is titrated by a 0.00200M solution of K2X (aq). A precipitate starts to form when 4.50mL of K2X (aq) have been added. Based on this data, determine the Ksp of M2X3. As usual, assume that aqueous solution volumes are additive.
Calculating the [PB2+] in a voltaic Pb-PbI2 cell using the recorded cell potential
a concentration cell was made by putting 5 mL of 0.050 M Pb(NO3)2 solution into one half-cell in a test plate. for the neighboring well in the test plate, weplaced 5 mL of a PbI2 solution that was made by mixing 9 mL of 0.050 KI solution with 3 mL of 0.050 M Pb(NO3)2 solution inside. Pb Electrodes were placed in eachcell, and a KNO3-soaked string was used as the salt bridge.data was collected and we recorded the average cell...

Question 6 (Extra Credit Challenge): When the sparingly soluble salt lead fluoride, PbF2, is added to an acidic solution with [H+] = 1.6 x 10–4 M, the resulting concentration of [Pb2+] after the salt dissolves is determined to be 7.75 x 10–5 M. (a) Determine the equilibrium constant for the dissolving of PbF2 in an acidic solution of H3O+ and (b) given Ka = 6.8 x 10–4, use the value determined in part a to calculate the Ksp for PbF2...
