Problem

A solution initially contains 4

\text{Ba}^{2+}

(aq), 8

\text{NO}_{3}^{-}

(aq), 6

\text{SO}_{4}^{2-}

(aq), and an excess of

\text{K}^{+}

(aq). After mixing, 2 units of solid

\text{BaSO}_{4}

(s) are observed while all other ions remain in solution. Write the balanced complete ionic equation that accounts for the observed change.
