question 11

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 hydrochloric acid is added to the buffer?

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