baking soda and vinegar

i think you have got a wrong concept.

neutralization products are not only H2O ang NaCl.

hydrochloric acid and sodium hydroxide react together to form H2O and

NaCl. nitric acid and sodium hydroxide react to form NaNO3 and H2O.

sulphuric acid and sodium hydroxide react to form Na2SO4 and H2O.

baking soda contains carbonate ions . carbonate ions react with

acetic acid(vinegar) to form CO2 and H2O.

ok?

好明顯001 d defination 讀得唔好

neutralization 既PRODUCT係 salt and water ONLY!!

1. Baking soda is metal carbonate, not alkali
Definition of alkali = base that is soluble in water
Definition of base = react with acid to form salt and water as the ONLY products.
Neutralization = acid + base

Baking soda + vinegar is not a neutralization process

Reason for producing CO2 for the reaction:
2H+ + CO3 2- --> H2O + CO2
