Answer

Answer:

  • B. $\text{CrO}_4^{2 - }$
  • C. $\text{Ba}^{2+}$

Explanation:

Step1: Define spectator ions

Spectator ions are ions that appear on both sides of a chemical - equation in the same form.

Step2: Analyze the given reaction

The reaction is $2\text{H}^++\text{CrO}_4^{2 - }+\text{Ba}^{2+}+2\text{OH}^-\rightarrow\text{Ba}^{2+}+\text{CrO}_4^{2 - } + 2\text{H}_2\text{O}$. We can see that $\text{CrO}_4^{2 - }$ and $\text{Ba}^{2+}$ are present on both the reactant and product sides in the same ionic form.

Step3: Identify non - spectator species

$\text{H}^+$ and $\text{OH}^-$ react to form $\text{H}_2\text{O}$, so they are not spectator ions. $\text{H}_2\text{O}$ is a product and not an ion in this context, so it is not a spectator ion.
