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)
