preparation of baking soda:
LABORATORY METHOD : in laboratory baking soda ( NAHCO3) can be prepared by saturating a cold solution of sodium carbonate with the carbon dioxide.
NA2CO3(aq)+co2(g)+H2O(l) ------>2NAHCO3
INDUSTRIAL PROCESS : sodium bicarbonate is obtained as intermediate product in the solvey's process for the manufacture of sodium carbonate from common salt.
NaCl + H2O + CO2 +NH3 --->NH4Cl +NaHCO3

preparation of washing soda :
it is obtained by heating baking soda which is obtained by passing seo2 gas through sodium chloride solution saturated with ammonia.
NaCl + H2O +CO2 + NH3 -----> NH4Cl + NaHC O3
recrystallization of sodium carbonate gives washing soda.
n a 2 c o 3 + 10 H2O ----Δ------> Na2C03.10H2O
