Consider the total ionic equation below.
2H⁺+ CrO²⁻₄+Ba²⁺+2OH⁻-->Ba²⁺+CrO²⁻₄+2H2O
What are the spectator ions in this equation?
H+ and OH-
H+ and Ba2+
CrO²⁻₄ and OH⁻
CrO²⁻₄ and Ba²⁺

Respuesta :

Answer:

The spectator ions in this equation are :

CrO²⁻₄ and Ba²⁺

Explanation:

Spectator ions : These are the ions which are present in the solution but do not take part in chemical reaction.They are present as such in  both reactant as well as product .

In this reaction,

1.H+ and OH- are combined and converted into water (H2O) : Changed to H2O

So , H+ and OH- are not Spectator ions

2.CrO²⁻₄ and Ba²⁺ are unchanged . Present as such in product and reactants

CrO²⁻₄ and Ba²⁺are Spectator ions

Answer:

CrO2- 4 and Ba2+

Explanation:

The answer is C
