The name trisodium phosphate is incorrect for the compound Na3PO4 because ____(A) this compound should be called trisodium monophosphate.(B) the sodium has a positive 3 charge.(C) you cannot use a prefix for the first element in a molecular compound.(D) you cannot use a prefix for the first element of an ionic compound.

Respuesta :

Answer:

(D) you cannot use a prefix for the first element of an ionic compound.

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:-

[tex]Na_3PO_4[/tex] is formed of cation, [tex]Na^+[/tex] and anion,[tex]PO_4^{3-}[/tex]

Thus, the name must be sodium phosphate.

The name is incorrect because - (D) you cannot use a prefix for the first element of an ionic compound.
