Question

identify all spectator ions in the reaction shown below. you may select more than one option. 2koh (aq) + sn(no3)2 (aq) → 2kno3 + sn(oh)2
phosphorus ion
strontium ion
sulfur ion
potassium ion
hydroxide ion
tin ion
nitrate ion
calcium ion

Explanation:

Step1: Write the complete ionic equation

$2K^+(aq)+2OH^-(aq)+Sn^{2 +}(aq)+2NO_3^-(aq)
ightarrow 2K^+(aq)+2NO_3^-(aq)+Sn(OH)_2(s)$

Step2: Identify spectator ions

Spectator ions are those that appear on both sides of the complete - ionic equation. Here, $K^+$ and $NO_3^-$ are present on both sides.

Answer:

Potassium ion, Nitrate ion
