Question

For the balanced ionic equation below: (Pb(NO₃)₂ (aq) +H₂SO₄ (aq)----->PbSO₄ (s) + 2 HNO₃ (aq) ), what are the spectator ions?

a) (Pb²+ ) and (SO₄²- )
b) (H⁺ ) and (NO₃⁻ )
c) (SO₄²- ) and (NO₃⁻ )
d) (Pb²+ ) and (H⁺ )

Answer 1

The spectator ions in the balanced ionic equation are H⁺ and NO₃⁻.

Step-by-step explanation:

In the balanced ionic equation, (Pb(NO₃)₂ (aq) +H₂SO₄ (aq) ----->PbSO₄ (s) + 2 HNO₃ (aq)), the spectator ions are (H⁺ ) and (NO₃⁻ ).

These ions do not participate in the reaction and remain the same on both sides of the equation.

The net ionic equation can be written as: Pb²+ (aq) + SO₄²- (aq) -----> PbSO₄ (s).
