Answer 3

acid+base-------->Salt+Water

Answer 4

did u got answer?

Answer 5

Is it nitric or nitrous?

Answer 6

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

Answer 7

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

Answer 8

"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 \(\huge NO_\color{red}2^-\)
