Answer:
I⁻ (aq) and Na⁺ (aq)
Explanation:
We have the chemical reaction:
BaI₂ + Na₂SO₄ → BaSO₄ + 2 NaI
However if you want to determine the spectator ions you need to write the states of compounds:
(aq) - ions dissolved in water
(s) - solid
Ba²⁺ (aq) + 2 I⁻ (aq) + 2 Na⁺ (aq) + SO₄²⁻ (aq) → BaSO₄ (s) + 2 Na⁺ (aq) + 2 I⁻ (aq)
The ions which does not change the state and remains dissolved in the solution are spectator ions. For our chemical reaction we have the following spectator ions:
I⁻ (aq) and Na⁺ (aq)
Mass is easier to get than the weight. weight is something that can change on the spot.<span />
