The aqueous solution of sodium carbonate(Na2CO3) is basic in nature due to having more hydroxide ions produced from the hydrolysis of carbonate ions (CO32- + H2O → HCO3– + OH–). The presence of fewer hydrogen ions and more OH– ions, increases the pH level of the Na2CO3 solution.
Why is na2co3 a basic salt?
Complete answer:
- Carbonate ion is a nucleophile so it would easily react with protons to form carbonic acid, H2CO3. - Now, we know that sodium hydroxide is a strong base and carbonic acid is a weak acid. - Therefore, sodium carbonate is a basic salt because it is a salt derived from a weak acid and strong base.
Why is na2co3 more basic than NaHCO3?
Ans: In the aqueous solution of Sodium carbonate there exist two sodium ions where as in the aqueous solution of Sodium bicarbonate there exists one ion. Presence of more metal ions in the aqueous solution of Sodium carbonate makes it basic than Sodium bicarbonate aqueous solution.
