Question

is the compound soluble or insoluble in water? baco₃ barium carbonate insoluble (s) soluble (aq)

Explanation:

According to solubility rules, most carbonates (\(CO_3^{2 - }\)) are insoluble in water, with exceptions like those of Group - 1 metals (e.g., \(Na_2CO_3\)) and \(NH_4^+\) (e.g., \((NH_4)_2CO_3\)). Barium (\(Ba^{2+}\)) is not in Group - 1, so \(BaCO_3\) does not fall into the soluble carbonate category.

Answer:

insoluble (s)
