    First, is this related to pH?

    Is it nitric or nitrous?

    Nitric ion is base. It means it has pH of greater than 7.

    @muhammad9t5 : "nitric ion" does not exist, you should use "nitrate ion".

    "nitric" is actually 'nitric acid' \(HNO_3\) ; its conjugate base is the 'nitrate ion' \(NO_3^-\) 'Nitrous acid' is \(HNO_2\) and its conjugate base is the 'nitrite ion' \(NO_2^-\) So, the Kb you are looking for should be the equilibrium constant of the reaction of the nitrite ion with water: \(NO_2^-+H_2O→HNO_2+OH^−\) CAREFUL : there is a mistake in the table provided by washington.edu formula for nitrite ion was badly written as the formula for the nitrate ion. It should read \(\huge NO_\color{red}2^-\)
