1.5

Explanation:

The acid, HCIO4 ionizes to give hydrogen ion (H+) and a conjugate base as follows:

HCIO4(aq) <---> H+(aq) + CIO4-(aq)

Hence, the H+ has also have a concentration of 0.0282 M

Mathematically, pH is expressed as:

pH = -log(H+), where H+ is the concentration of hydrogen ion.

So, for HCIO4

pH = - log (0.0282 M)

pH = - (-1.5497) (The two minus signs will cancel out)

pH = 1.5497

Round the pH value to the nearest tenth as 1.5

Thus, the pH of 0.0282 M of HCIO4 is 1.5, also HCIO4 is strongly acidic since pH values less than 7 are regarded as acidic.
