If you add a few drops of acetic acid to a test tube containing (i) distillated water and (ii) aqueous solution of sodium hydrogen carbonate, what would you observe ? If a reaction takes place in any one of the above two cases, list its two observations.
(i) While adding few drops of acetic acid, it releases ions and the solution will become acidic and pH value of solution will be go down.
(ii) Chemical reaction -
When an acetic acid react with sodium hydrogen carbonate it decomposes into water and carbon dioxide.
