    Answer:

    5.46

    Explanation:

    From the question,

    pH this can be defined as the acidity or alkalinity of a solution.

    The expression for pH is given as

    pH = -log(H⁺)…………………. Equation 1

    Where H⁺ = Hydrogen ion of HCL

    Given: H⁺ = 3.5×10⁻⁶ M

    Substitite this value into equation 1

    pH = -log(3.5×10⁻⁶)

    pH = 5.46

    Hence the pH of HCl is 5.46
