Why solution of Na2CO3 is basic?

Sodium carbonate (Na2CO3) dissociates in water to form sodium ions (Na+) and carbonate ions (CO3^2-). The carbonate ion can react with water to form bicarbonate ion (HCO3-) and hydroxide ion (OH-), which makes the solution basic. The presence of hydroxide ions increases the pH of the solution, leading to a basic nature.
