So how does this workout? mixing solutions?

Question

A solution of 100.0 mL of 0.200 M KOH is mixed with a solution of 200.0 mL of 0.150 M NiSO4.

(a) Write the balanced chemical equation for the reaction that occurs. (Type your answer using the format H2O for H2O and (NH4)2CO3 for (NH4)2CO3. Use the lowest possible coefficients.)
___NiSO4(aq) +_____KOH(aq) _____ ___(s) + ___ _____(aq)

(b) What precipitate forms?


(c) What is the limiting reactant?


(d) How many grams of this precipitate form?
g

(e) What is the concentration of each ion that remains in solution?
Ni2+
____ M

K+
______M

SO42-
______ M


this is crazy, how do I do this?

thanks!

Answer 1

(a) NiSO4(aq) + 2KOH(aq) ---> Ni(OH)2(s) + K2SO4(aq)
(b) Ni(OH)2
(c) KOH
(d) 0.01Mol x (molecular weight of Ni(OH)2)
(e) Ni++: 0.02Mol/0.3L =
K+: 0.02Mol/0.3L =
SO4--: 0.1M
