This is not true. The sulfide ion is a stronger base than the nitrate ion. This is because nitrogen and oxygen are very electronegative, This creates a stable anion with very little affinity for hydrogen ions. Sulfur is much less electronegative and so the sulfide ion is less stable. So it has a much higher affinity of a hydrogen ion.
