I am 16 and i was playing with baking soda and citric acid and I was wondering what is reacting and how do they react and also I wanted to write an equation.

Code: Select all

NaHCO3 + C6H8O7 = ?

Citric acid is an organic compound (or I think it is) and they haven't taught us that in school yet and I am just very curious. I know it's a neutralization reaction and will produce

Code: Select all

H2O

and

Code: Select all

CO2

Thank you in advance!

Citric acid contain three acidic groups.Carboxyl group R-COOH.

C₆H₈O₇ = HOOC-CH₂-CHOH(COOH)-CH₂-COOH

Reaction now is 3 NaHCO₃ + HOOC-CH₂-CHOH(COOH)-CH₂-COOH => 3 H₂O + 3 CO₂ + NaOOC-CH₂-CHOH(COONa)-CH₂-COONa.

You get Trisodium citrate, water and carbondioxide.
