2 agno₃ (aq) + k₂so₄ (aq) → 2 kno₃ (aq) + ag₂so₄ (s)
the spectator ions in the reaction shown are
○ hydrogen ion and hydroxide ion.
○ silver ion and nitrate ion.
○ potassium ion and sulfate ion.
○ potassium ion and nitrate ion.
○ silver ion and sulfate ion.

Explanation:

Step1: Write the complete ionic equation

For \(2AgNO_{3}(aq)+K_{2}SO_{4}(aq)\to2KNO_{3}(aq)+Ag_{2}SO_{4}(s)\), in aqueous solution:
\(2Ag^{+}(aq)+2NO_{3}^{-}(aq)+2K^{+}(aq)+SO_{4}^{2 -}(aq)\to2K^{+}(aq)+2NO_{3}^{-}(aq)+Ag_{2}SO_{4}(s)\)

Step2: Identify spectator ions

Spectator ions are ions that do not participate in the reaction (appear on both sides of the equation). Here, \(K^{+}\) and \(NO_{3}^{-}\) are spectator ions.

Step3: Write the net - ionic equation

Cancel out the spectator ions (\(K^{+}\) and \(NO_{3}^{-}\)) from the complete ionic equation. The net - ionic equation is \(2Ag^{+}(aq)+SO_{4}^{2 -}(aq)\to Ag_{2}SO_{4}(s)\)

Answer:

For the first question (net - ionic reaction), the answer is \(2Ag^{+}+SO_{4}^{2 -}\to Ag_{2}SO_{4}\).
For the second question (spectator ions), the answer is potassium ion and nitrate ion.
