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

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!
