why is the reaction mixture extracted with sodium bicarbonate?give an equation and explain its relevance.
Would you mind letting us know what it is you're extracting? My crystal ball isn't working very well tonight. :-)
But my best guess, knowing ONLY that NaHCO3 is being used---probably you have a carboxylic acid (RCOOH) in a procedure and the NaHCO3 will neutralize the excess RCOOH.
