Enter the formula for the compound cobalt(II) phosphate. Express your answer as a chemical formula.
alexira [117]

Answer:

Co_3(PO_4)_2

Explanation:

Naming of the ionic compounds:-

  • The name of the cation is written first and the the name of the anion is written after the name of the cation separated by single space.
  • The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
  • In case of transition metals, the oxidation state are written in roman numerals in bracket in front of positive ions.

Hence, given ionic compound:-

Cobalt(II) phosphate

So, Cobalt will have a positive charge of +2

Phosphate is PO_4^{3-}

So, the formula is :-

Co         PO_4^{3-}

2                    3

Co_3(PO_4)_2
