2 AgNO₃(aq)+ K₂SO₄(aq)→ 2 KNO₃(aq)+ Ag₂SO₄(s) The spectator ions in the reaction shown are A)silver ion and nitrate ion. B)potassium ion and sulfate ion. C)potassium ion and nitrate ion. D)silver ion and sulfate ion. E)hydrogen ion and hydroxide ion.

Question

Quizplus · Accepted Answer

The spectator ions are the ions that do not participate in the chemical reaction and are present on both sides of the chemical equation. In this reaction, the potassium ion (K+) and nitrate ion (NO3-) are present on both sides of the equation while the silver ion (Ag+) and sulfate ion (SO4^2-) are involved in the formation of a precipitate. Therefore, the correct answer is choice C, potassium ion and nitrate ion.

2 AgNO3(aq)+ K2SO4(aq)→ 2 KNO3(aq)+ Ag2SO4(s)

2 AgNO₃(aq)+ K₂SO₄(aq)→ 2 KNO₃(aq)+ Ag₂SO₄(s)
