Calculate the ph in an aqueous 0.120 m nitrous acid solution.
Answers: 2
is a weak acid so first of all we solve for 
and then figure out the pH.
= 
and the equilibrium expression for this would be written as:![Ka=\frac{[H_3O^+][NO_2^-]}{HNO_2}](/tpl/images/0075/4998/f7336.png)
![[H_3O^+]=7.3*10^-^3M](/tpl/images/0075/4998/899ac.png)
![pH=-log[H_3O^+]](/tpl/images/0075/4998/6e71a.png)
