Suppose a buffer solution is made from formic acid (HCHO2) and sodium formate (NaCHO2). What isthe net ionic equation for the reaction that occurs when a small amount of sodium hydroxide is added to the buffer?A)NaOH(aq)+ HCHO2(aq) -> NaCHO2(aq) + H2O(l)B) Na+(aq) + HCHO2(aq) -> NaH(aq) + HCO2+(aq)C) OH-(aq) + HCHO2(aq) -> CHO2-(aq) + H2O(l)D) H3O+(aq) + OH-(aq) -> 2H2O(l)E) NaOH(aq) + H3O+(aq) Na+(aq) + 2H2O(l)

Answer:

C) OH⁻(aq) + HCHO₂(aq) → CHO₂⁻(aq) + H₂O(l)

Explanation:

The net ionic equation is a chemical equation for a reaction that lists only those species participating in the reaction.

When there is an addition of base in a buffer, the acid will react with the base to produce water and conjugate base. Thus, the reaction is:

OH⁻(aq) + HCHO₂(aq) → CHO₂⁻(aq) + H₂O(l)

-You don't write the sodium of NaOH because is not involved in the reaction-

I hope it helps!

The study of chemicals and bonds is called chemistry. when two or more elements join together to form a new compound is called a combination reaction.

The correct answer is C.

The reaction is involved in the reaction is as follows:-[tex]OH^{-} (aq) + HCHO_2(aq) ----> CHO_2^-(aq) + H_2O(l)[/tex]

What is a buffer solution?

  • The solution which has the fixed ph is called buffer solution. The Ph of buffer solution will not change by adding any type of compound net ionic equation is a chemical equation for a reaction that lists only those species participating in the reaction.

In the ionic reaction, the charges must be equal in both the ions When there is an addition of base in a buffer, the acid will react with the base to produce water and conjugate the base.

Thus, the reaction is:[tex]OH^{-}(aq) + HCHO_2(aq) ---> CHO_2^{-}(aq) + H_2O(l)[/tex]

Hence, the correct option is C.
