Suppose a Buffer Solution Is Made from Formic and (HCHO₂)and $\to$

Suppose a buffer solution is made from formic and (HCHO₂) and sodium formate (NaCHO₂) .What is the net ionic equation for the reaction that occurs when a small amount of hydrochloric acid is added to the buffer?

A) H₃O⁺(aq) + OH^-(aq) $\to$ 2H₂O(l)
B) H₃O⁺(aq) + HCHO₂(aq) $\to$ H₂O(l) + H₂CHO₂⁺(aq)
C) HCl(aq) + OH^-(aq) $\to$ H₂O(l) + Cl^-(aq)
D) HCl(aq) + CHO₂^-(aq) $\to$ HCHO₂(aq) + Cl^-(aq)
E) H₃O⁺(aq) + CHO₂^-(aq) $\to$ HCHO₂(aq) + H₂O(l)
