Question

Give the spectator ions for the reaction that occurs when aqueous solutions of H 2SO 4 and KOH are mixed.

Answer 1

The spectator ions is:
`K^+` and
`SO^(2-)_4`

Step-by-step explanation:

The equation of reaction between H₂ SO₄ and KOH is:

`H_2SO_(4(aq)) + 2KOH _(aq) \to K_2SO_(4(aq)) +2H_2O _((l))`

Rewriting this equation as ionic;

`[2H^(+) + SO^(2-)_4 + 2K^+ +2OH^- \to 2K^+ SO_4^(2-) + 2H_2O ]`

Spectators ions are ions present on both sides of the ionic equation by the same quantity but do not take part in the net reaction.
