Question

multiple choice 1 point write the formula for cobalt (ii) phosphate cop co2p3 co3p2 cop3 previous

Explanation:

Step1: Determine ion charges

Cobalt (II) has a charge of $Co^{2 +}$, phosphate ion is $PO_{4}^{3-}$.

Step2: Use charge - balance

To balance the charges, we need 3 cobalt (II) ions ($3\times( + 2)=+6$) and 2 phosphate ions ($2\times(- 3)= - 6$).

Answer:

C. $Co_{3}P_{2}$
