Answer:
The pH of a 0.0025 m solution perchloric acid is 2.60.
Explanation:
Concentration of perchloric acid = 0.0025 M
[tex]HClO_4\rightarrow H^++ClO_{4}^{-}[/tex]
Perchloric acid is monobasic acid with one [tex]H^+[/tex].
[tex][HClO_4]=[H^+]=[ClO_{4}^{-}]=0.0025 M[/tex]
[tex]pH=-\loh[H^+][/tex]
[tex]pH=-\log[0.0025 M]=2.60[/tex]
The pH of a 0.0025 m solution perchloric acid is 2.60.
