what are the spectator ions in the reaction between koh and hno3?
h+ and no3-
k+ and no3-
k+ and h+
h+ and oh-

Explanation:

Step1: Write the balanced molecular equation

$$KOH(aq)+HNO_{3}(aq) ightarrow KNO_{3}(aq)+H_{2}O(l)$$

Step2: Write the total ionic equation

$$K^{+}(aq)+OH^{-}(aq)+H^{+}(aq)+NO_{3}^{-}(aq) ightarrow K^{+}(aq)+NO_{3}^{-}(aq)+H_{2}O(l)$$

Step3: Identify spectator ions

Spectator ions are ions that appear on both sides of the total ionic equation. Here, \(K^{+}\) and \(NO_{3}^{-}\) are present on both sides.

Answer:

\(K^{+}\) and \(NO_{3}^{-}\) (corresponding to the option \(K^{+}\) and \(NO_{3}^{-}\))
