3. (A)Please calculate the ionic strength of a solution containing 0.01 M K2SO4 and 0.01 M NaCl. (5 分)
#603801
(B) A solution of 1 liter contains Fe3+,SCN-,and Fe(SCN)2+ and reacts following the equation shown as Fe3+(pale yellow) + SCN-(colorless) ↹Fe(SCN)2+(red) to an equilibrium state of red color.
