Neutral Salt
A salt whose aqueous solution has a pH of 7 because neither of its ions hydrolyses appreciably.

Dimensionless
In depth
Neutral salts derive from a strong acid and a strong base, so both ions are conjugates too weak to react with water. They are useful for adjusting ionic strength without disturbing pH, and are the salts of choice for salt bridges.
Examples in the real world
Sodium chloride, potassium nitrate and sodium sulfate all give neutral solutions.
