Dear Student,

◆ Answer -

Sodium carbonate

● Explaination -

• Sodium carbonate is basic salt while all others are neutral salts.
• Sodium carbonate (Na2CO3) is a salt of strong base (NaOH) and weak base (H2CO3). Hence, it is weak base.
• All other salts (NaNO3, Na2SO4, NaCl) are formed by strong base (NaOH) with strong acids (HNO3, H2SO4, HCl). Hence, all other salts are neutral in nature.

Thanks dear. Hope this helps you..
