One of the reactions which happens in an aqueous solution of carbon dioxide is:
H₂CO₃(aq) ⇄ HCO₃^-(aq) + H⁺(aq)
Which one of the following statements best describes the effect of adding hydroxide (OH^-(aq)) to a solution containing H₂CO₃?

Question

One of the reactions which happens in an aqueous solution of carbon dioxide is:

H₂CO₃(aq) ⇄ HCO₃^-(aq) + H⁺(aq)

Which one of the following statements best describes the effect of adding hydroxide (OH^-(aq)) to a solution containing H₂CO₃?

Answer

the OH -  will react with the H +  to form water causing less H 2 CO 3  to dissociate, increasing the amount of H 2 CO 3

Answer

OH -  is not involved in this reaction so it will have no effect on the amount of H 2 CO 3

Answer

the OH -  will react with the H +  to form water and more H 2 CO 3  will dissociate, reducing the amount of H 2 CO 3
