$Sodium and chloride ions.........$ $"Sodium and chloride ions........."$

Explanation:

We write the equation for the formation of $B a S O_{4} (s)$ $BaSO_4(s)$ as:

$B a C l_{2} (a q) + N a_{2} S O_{4} (a q) \to B a S O_{4} (s) ⏐ ↓ + 2 N a C l (a q)$ $BaCl_2(aq) + Na_2SO_4(aq) rarr BaSO_4(s)darr + 2NaCl(aq)$

Alternatively, we could write the net ionic equation:

$B a^{2 +} + S O_{4}^{2 -} \to B a S O_{4} (s) ⏐ ⏐ ↓$ $Ba^(2+) + SO_4^(2-) rarr BaSO_4(s)darr$

In other words, the $N a^{+}$ $Na^+$ , and $C l^{-}$ $Cl^-$ ions are along for the ride. The are passengers, spectators, and play no part in the macroscopic reaction.
