On a 10-fold dilution of a strong acid, the pH will increase.

Proof:

Lets take initial concentration of Acid as 10 M, So, as

pH = - log [H ⁺]

Putting value of [H⁺]

pH = - log (10)

pH = - 1

After 10 fold Dilution, the concentration iwill be 1 M, So,

pH = - log [H⁺]

Putting value of [H⁺]

pH = - log (1)

pH = 0

So, with 10 fold dilution the pH increases.
