    Answer:

    4.46

    Explanation:

    Applying,

    pH = -log(H⁺)………………….. Equation 1

    Where H⁺ = Hydrogen ion concentration of HCl solution

    From the question,

    Given: H⁺ =  3.5×10⁻⁵ M

    Substitute these values into equation 1

    pH = -log(3.5×10⁻⁵)

    pH = 4.46

    Hence the pH of HCl solution is 4.46
