Answer:

The pH of a 0.0025 m solution perchloric acid is 2.60.

Step-by-step explanation:

Concentration of perchloric acid = 0.0025 M

$HClO_4\rightarrow H^++ClO_(4)^(-)$

Perchloric acid is monobasic acid with one
H^+ .

[HClO_4]=[H^+]=[ClO_(4)^(-)]=0.0025 M

$pH=-\loh[H^+]$

$pH=-\log[0.0025 M]=2.60$

The pH of a 0.0025 m solution perchloric acid is 2.60.
