Quizplus · Accepted Answer

When solutions of NaOH(aq), Ca(ClO4)2(aq), and Ba(OH)2(aq) are mixed, the following reaction occurs:

2NaOH(aq) + Ca(ClO4)2(aq) + Ba(OH)2(aq) → Ca(OH)2(s) + Ba(OH)2(s) + 2NaClO4(aq)

The compounds Ca(OH)2 and Ba(OH)2 are both insoluble in water and will precipitate out of solution, while NaClO4 will remain in solution. Therefore, the compound formed as a precipitate is Ca(OH)2.
