Question

Use the solubility rules and the periodic table to predict the product that will precipitate out in the reaction.

K2SO4(aq) + Ba(NO3)2(aq) → ?

A.
KNO3
B.
Ba(NO3)2
C.
K2SO4
D.
K2Ba
E.
BaSO4

Answer 1

It is E- BaSO4

Step-by-step explanation:

Answer 2

E - BaSO4

According to solubility rules, "All Sulfates except Calcium, Strontium, Barium, Mercury, Lead(II), and Silver are soluble."

This means that BaSO4 would be a solid formed in the reaction, or a precipitate.

A and B would be incorrect as all nitrates are soluble. C would be incorrect as no replacement/displacement was made. D would be incorrect as that answer does not follow any reaction properly.

Therefore, E (BaSO4) would be the correct answer.

Hope this helps!
