Acid-Base Reaction Between Baking Soda and Vinegar

CHEM-BNDJIX

A classic demo that you see at science fairs is the baking soda and vinegar volcano from a soda bottle.

Which of the following is the chemical reaction behind this “eruption”?

A

${ NaHCO }_{ 3 }(aq)\space +\space C{ H }_{ 3 }COOH(aq)\space \longrightarrow \space C{ H }_{ 3 }COONa(aq)\space +\space { H }_{ 2 }O(l)\space +\space C{ O }_{ 2 }(g)$

B

${ { Na }_{ 2 }CO }_{ 3 }(aq)\space +\space 2C{ H }_{ 3 }COOH(aq)\space \longrightarrow \space 2C{ H }_{ 3 }COONa(aq)\space +\ { H }_{ 2 }O(l)\space +\ C{ O }_{ 2 }(g)$

C

${ NaHCO }_{ 3 }(aq)\space +\space HCl(aq)\space \longrightarrow \space NaCl(aq)\space +\space { H }_{ 2 }O(l)\space+\ C{ O }_{ 2 }(g)$

D

${ { Na }_{ 2 }CO }_{ 3 }(aq)\space +\space 2HCl(aq)\space \longrightarrow \space 2NaCl(aq)\space +\space { H }_{ 2 }O(l)\space +\space C{ O }_{ 2 }(g)$
