a. When 25.0 mL of
a 7.18×10-4 M ammonium
sulfide solution is combined
with 15.0 mL of
a 6.69×10-4 M nickel(II)
iodide solution does a precipitate form? fill in
the blank 1 (yes or no)For these conditions the Reaction
Quotient, Q, is equal to .
b. When 18.0 mL of
a 8.05×10-4 M chromium(III)
acetate solution is combined
with 18.0 mL of
a 9.71×10-4 M ammonium
phosphate solution does a precipitate form? fill
in the blank 1 (yes or no)For these conditions the Reaction
Quotient, Q, is equal to .
c. Consider these compounds:
Complete the following statements by entering the letter(s)
corresponding to the correct compound(s). (If more than one
compound fits the description, include all the relevant compounds
by writing your answer as a string of characters without
punctuation, e.g, ABC..Without doing any calculations it is
possible to determine that cobalt(II)
sulfide is more soluble than fill in the blank
1, and cobalt(II) sulfide is less
soluble than fill in the blank 2.It is not possible to
determine whether cobalt(II) sulfide is
more or less soluble than fill in the blank 3 by simply
comparing Ksp values.
