   Yes, I think it would with time and humidity. Sodium bicarbonate in its box   
   is often put into refrigerators to absorb smells. To be regenerated requires   
   heat. But to do so would release CO2 and convert sodium bicarbonate to   
   sodium carbonate,   
      
   2NaHCO3 -> Na2CO3 + CO2 + H2O   
      
   So most people just throw away the box when it becomes stale.
