The chemical reaction that occurs when effervescent tablets are placed in water is as follows:
Reaction in Words:
Citric Acid + Sodium Bicarbonate yields Water + Carbon Dioxide + Sodium Citrate
Reaction in Symbols:
~C_6H_8O_7 + ~3NaHCO_3 -> ~3H_2O + ~3CO_2 + ~Na_3C_6H_5O_7
How the Reaction Occurs:
- Before the tablet is dissolved, the citric acid and sodium bicarbonate are in solid form and unable to react with one another.
- In order for the citric acid and sodium bicarbonate to react, they must be dissolved in water. Dissolving breaks the two chemicals into their positive and negative ions. This enables them to come in contact and react with one another.
Why do effervescent tablets dissolve in water?
- Citric acid is an acid and sodium bicarbonate is an...
