When sodium sulfide reacts with cobalt (II) acetate in water, cobalt (II) sulfide and sodium
acetate are produced.
(a) Write the balanced (i) molecular; (ii) total ionic; and (iii) net ionic equations. Include
phases.
(b) If 4.00 mL of 0.250 mol/L sodium sulfide solution are reacted with 6.80 mL of 0.350
mol/L cobalt (II) acetate solution, what mass of precipitate is formed? Show all your work,
including a complete dimensional analysis.
(c) Assume the reaction proceeds to completion with 100% yield and that the excess
reactant could not be recycled. What is the mass of wasted starting material?
