Answer to Question #63904 in General Chemistry for Lindsey Moss

Question

A solution of 250.0 mL of 0.450 M potassium hydroxide is mixed with a solution of 340 mL of 0.240 M nickel (II) sulfate. (a) Write the balanced chemical equation of the reaction that occurs. (b) Name the precipitate that is formed. (c) What is the limiting reactant in this reaction? (d) How many grams of the precipitate will form? (e) What is the concentration of each ion that remains in solution?

Answer 1

a) NiSO4 + 2KOH = Ni(OH)2 + K2SO4
b) Ni(OH)2 - nickel hydroxide
c) NISO4 is a limiting reagent
d) The mass of Ni(OH)2 is 5.1 g.
e) C(Ni2+) = 0.044 M, C(SO42-) = 0.14 M and C(K+) = 0.19 M
