11. Imagine that the unknown solution contains potassium bicarbonate, which is frequently used as a pH buffering agent in foods and medications, and like sodium bicarbonate, will react with an acid. For the reaction between potassium bicarbonate solution and acetic acid solution (the reactants), write the (1) balanced molecular equation, (2) the complete ionic equation, (3) the net ionic equation AND identify the spectator ions, if any.

Respuesta :

Answer :

1)

Balanced Molecular equation -

KHCO₃ + HC₂H₃O₂ →   KC₂H₃O₂ + CO₂ + H₂O

(Potassium bicarbonate) + ( acetic acid)

2)

K⁺ + HCO⁻₃ + HC₂H₃O₂ → K⁺ + C₂H₃O⁻₂ + CO₂ + H₂O

3)

As we knw that the spectator ion are that ion which comes at both sides of the equation,

Here we can see that K⁺ ion comes both side of the equation

So, we get

K⁺ is the spectator ions.

Net ionic equation -

HCO⁻₃ + HC₂H₃O₂  →  C₂H₃O⁻₂ + CO₂ + H₂O
