Acetic Acid And Bicarbonate Reaction
Blistering soda and vinegar experiment
This easy to undertake and safe experiment allows students to find many of the features of chemical reactions as well as the 3 physical states of thing. This experiment clearly distinguishes a chemic change from concrete change.
Run across the topics Chemical reactions and Physical change or chemical change? for more than information.
The materials
- Baking soda - Chemical name, sodium bicarbonate with formula NaHCOiii.
- Vinegar - A dilute solution of acetic acid in water. Acetic acid is also known as ethanoic acid, with the formula CHiiiCOOH.
- A beaker or jar.
The chemical reaction
When baking soda is mixed with vinegar, something new is formed. The mixture quickly foams upwardly with carbon dioxide gas. If enough vinegar is used, all of the blistering soda can be made to react and disappear into the vinegar solution.
The reaction is:
Sodium bicarbonate and acetic acrid reacts to carbon dioxide, water and sodium acetate.
NaHCO3 + CH3COOH 
CO2 + H2O + Na CH3COO
The physical changes
The solid baking soda was placed in liquid vinegar producing carbon dioxide gas, which is evident because of the formation of bubbles in the foaming mixture. Eventually all of the solid dissolved and reacted producing a new liquid solution.
During the reaction, a solid and liquid have been chemically reacted to grade a gas and a liquid. This experiment can also be used to explain foams, as liquids or solids containing gas bubbles.
Safety and disposal
Although both reactants are household chemicals and foodstuffs, circumspection should exist taken not to get splashes in the eyes and apparel should be protected. The products of the reaction are relatively safe (Remember - no chemicals should be touched) and tin can be tending of by washing down the sink with plenty of water.
