Suppose a Buffer Solution Is Made from Formic Acid (HCHO₂)and

Multiple Choice

Suppose a buffer solution is made from formic acid (HCHO₂) and sodium formate (NaCHO₂) .What is the 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)
