Question

When CoBr₂ (aq) and Li₃PO₄ (aq) are mixed, which precipitate forms (if any)?

1-LiBr

2 -Li₃Br₂

3-CoPO₄

4-Co₃(PO₄)₂

5-No precipitate

Answer 1

When CoBr₂ (aq) and Li₃PO₄ (aq) are mixed, Co₃(PO₄)₂ precipitate forms.

Step-by-step explanation:

The addition of CoBr₂ (aq) and Li₃PO₄ (aq) results in a precipitation reaction. The insoluble salt that forms is Co₃(PO₄)₂. This reaction can be represented by the equation:

CoBr₂ (aq) + 3 Li₃PO₄ (aq) →→ Co₃(PO₄)₂ (s) + 6 LiBr (aq)
