Acetic Acid + Sodium Bicarbonate
Baking soda and vinegar experiment
This easy to undertake and safe experiment allows students to find many of the features of chemical reactions besides every bit the three physical states of affair. This experiment clearly distinguishes a chemical modify from physical change.
Meet the topics Chemic reactions and Physical modify or chemical change? for more than information.
The materials
- Baking soda - Chemical proper noun, sodium bicarbonate with formula NaHCOthree.
- Vinegar - A dilute solution of acetic acid in water. Acerb acid is likewise known as ethanoic acid, with the formula CH3COOH.
- A chalice 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 baking soda tin can exist fabricated to react and disappear into the vinegar solution.
The reaction is:
Sodium bicarbonate and acetic acid reacts to carbon dioxide, water and sodium acetate.
NaHCO3 + CHthreeCOOH 
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. Somewhen all of the solid dissolved and reacted producing a new liquid solution.
During the reaction, a solid and liquid take been chemically reacted to grade a gas and a liquid. This experiment can as well be used to explain foams, as liquids or solids containing gas bubbles.
Safety and disposal
Although both reactants are household chemicals and foodstuffs, caution should be taken not to get splashes in the optics and dress should be protected. The products of the reaction are relatively prophylactic (Remember - no chemicals should be touched) and tin be disposed of past washing down the sink with plenty of h2o.
