Answer 3

This is a neutralization reaction.

NaHCO3 is sodium bicarbonate. The bicarbonate ion, HCO3-, is amphiprotic and can act as a weak base in this case. It does this by further dissociating into hydroxide and carbon dioxide in this equilibrium reaction:

\[HCO_3^- \leftarrow \rightarrow OH^- + CO_2\]
It's the hydroxide coming from here that will neutralize the acid in this reaction.

C4H6O6 is tartaric acid. Because it actually has TWO carboxyl groups, one on each end (see here: http://upload.wikimedia.org/wikipedia/commons/0/05/Tartaric_acid.svg), tartaric acid requires TWO equivalents of NaHCO3 to be neutralized completely.

As with any neutralization reaction, in this case, water is produced, as is the sodium salt of tartaric acid. However, there is also a molecule of CO2 produced for every molecule of NaHCO3 that reacts as you can see from the equilibrium reaction above. So the net reaction is the following:

\[2NaHCO_3 + C_4H_6O_6 \rightarrow C_4H_4O_6Na_2+2H_2O + 2CO_2\]
Let me know if you have any questions!
