Sodium carbonate when dissolved in water is hydrolysed to form a weak acid, carbonic acid and a strong base sodium hydroxide. Hence, an aqueous solution of sodium carbonate is alkaline in nature.....

Since the salt NaHCO3 in aq soln gives strong base and weak acid, so predominance of basic nature lies in the salt. Use- component of baking powder and antacid component to neutralize acidity in the body.....
