Question

List two observations which you make when you add a pinch of sodium hydrogen carbonate to acetic acid in a test tube. Write chemical equation for the reaction that occurs.

Answer 1

CH3COOH + NaHCO3 -------------> CH3COONa + CO2    +   H2O 
 (ethanoic     (sodium hydogen        (sodium         (Carbon      (water)
   acid)              carbonate)                  acetate)        di oxide )
     
 HERE, in this reaction ethanoic acid (acetic acid)   reacts with sodium hydrogen carbonate and leaves the product sodium acetate , carbon di oxide and water
             
              CO2 that us carbon di oxide can be tested with lime water if carbon di oxide gas passes the lime water it turns milky . .....
 
            HOPE THIS WILL HELP YOU.... ALL THE BEST .... *=*


 
     

Answer 2

Ch3cooh+ Nahco3 -----> Ch3cooNa + Co2 + H20

It releases carbon dioxide during the reaction and it can be tested using lime water which produces a white precipitate on passing the co2 gas upon it.
