Question

enter the ions present in a solution of na₃po₄. express your answers as chemical formulas separated by a comma. offset subscripts and charges on each ion; for charges, write the number before the + or - sign. view available hint(s)

Explanation:

Step1: Identify the compound type

$\ce{Na3PO4}$ is an ionic compound, specifically a salt. Ionic salts dissociate in water into their constituent ions.

Step2: Determine the cations and anions

Sodium phosphate ($\ce{Na3PO4}$) is composed of sodium ions ($\ce{Na+}$) and phosphate ions ($\ce{PO4^{3-}}$). From the formula, the subscript of $\ce{Na}$ is 3, indicating that 3 moles of $\ce{Na+}$ ions are produced for every 1 mole of $\ce{PO4^{3-}}$ ion when $\ce{Na3PO4}$ dissociates in solution. The dissociation reaction is: $\ce{Na3PO4(aq) -> 3Na+(aq) + PO4^{3-}(aq)}$

Answer:

$\ce{Na+}$, $\ce{PO4^{3-}}$
