what is the approximate expected pH of a 0.030 M HNO3 solution?


Answer:- 
 HNO3, HCl ,H2SO4 are the  strong acid .

The formula for strong acid is  
                                                 pH = - log [H+] 
    
Dissociation reaction of HNO3 is
                                          HNO3 ---> H+    + NO3-

             So concentration of [H+]  = 0.030M 

                                             pH = - log 0.030 

                                            pH = 1.52
Answer pH = 1.52
how to calculate PH
