A 0.10 mol/L aqueous solution of sodium nitrate has a pH of 7.00.
Sodium nitrate is the salt formed by the reaction of nitric acid with sodium hydroxide.
The equation for the reaction is
In ionic form, the equation is
It has no tendency to act as a base in aqueous solution.
In the same way, the conjugate acid of the strong base
∴ The pH of a neutral solution is 7.00.
