SODIUM BICARBONATE IS HYDROLIZED TO FORM HYDROXIDE
AND BICARBONATE ION
SO IT IS ALKALINE IN NATURE DUE TO PRESENCE OF THESE 2 IONS IN SOLUTION SO PH OF AQUEOUS SOLUTION OF NA2CO3 IS MORE THAN 7
CO3^-2+H2------>HCO-3+OH-

Na₂CO₃ or Sodium carbonate is actually washing soda. When it is stirred in water, it dissociates into 2 types of ions.
The cation (positive ion) is monovalent cation sodium ion- Na⁺
and anion (negative ion) is divalent anion carbonate ion (a polyatomic ion) CO₃²⁻
Therefore, it can be written as:- 
Na₂CO₃------------> 2Na⁺ CO₃²⁻ 
So, for every carbonate ion, there are 2 sodium ions.
