Given the following list from the activity series of metals (from most active to least active) k, na, al, mn, cr, cd, co, pb, hg which reaction would you not expect to occur?
1. co²⁺(aq) + al(s) → al³⁺(aq) + co(s) 2. cd(s) + pb²⁺(aq) → pb(s) + cd²⁺(aq) 3. all of the listed reactions will occur. 4. na(s) + mn²⁺(aq) → na⁺(aq) + mn(s) 5. al³⁺(aq) + cr(s) → cr³⁺(aq) + al(s)

Using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 pb+2(aq) + 2cl -(aq). if the value of ksp was determined to be only 1.2 x 10-2: too much solid has dissolved. additional precipitate is forming. the solution is unsaturated. the ions are now combining to reduce their concentrations.
