The small ii s should be II. and in parentheses as (II). Pb^+2 + 2OH^- ==> Pb(OH)2(s). If excess OH^- is added, the Pb(OH)2(s) dissolves to form a complex ion. Pb(OH)2(s) + 2OH^- ==> Pb(OH)4-2

You can't understand if you don't try. You could help by explaining exactly what you don't understand instead of leaving me hanging out there with no idea of which direction to go to help. mols = M x L. You have M = 0.15M in the problem. You have 425 mL (0.425L) volume in the ...
