Water has a ph of 7. if 0.1 ml (about one drop) of 1.0 m hno3 is added to 100 ml of water, the result is a solution with a concentration of 0.001 m hno3. what is the ph of 0.001 m hno3

1.0 m [tex]HNO_3[/tex] is added to 100 ml of water, the result is a solution with a concentration of 0.001 m [tex]HNO_3[/tex] and the ph of 0.001 M [tex]HNO_3[/tex] is 3

What is  [tex]_PH[/tex] ?

pH historically denoting "potential of hydrogen" (or "power of hydrogen") is a scale used to specify the acidity or basicity of an aqueous solution

GIven ,

[tex]H^{+}[/tex] = [tex]10^{-3}[/tex] M

we have the formula for

[tex]_PH[/tex] = - log [[tex]H^{+}[/tex]]

[tex]_PH[/tex] = - log [ [tex]10^{-3}[/tex] ]

       = 3 log 10

  [tex]_PH[/tex] = 3

       

Hence, [tex]_PH[/tex] of water is 7 but after adding 1 drop (0.001 m [tex]HNO_3[/tex] ), It changes to 3.
