question 57

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)
