Assuming that no equilibria other than dissolution are involved, calculate the concentration of all solute species in each of the following solutions of salts in contact with a solution containing a common ion. State whether or not it is appropriate to neglect the changes in the initial concentrations of the common ions.
(a) TlCl(s) in 0.025 M TlNO3
(b) BaF2(s) in 0.313 M KF
(c) MgC2O4 in 2.250 L of a solution containing 8.156 g of Mg(NO3)2
(d) Ca(OH)2(s) in an unbuffered solution initially with a pH of 12.700
