    HCl is a strong acid, so we use the following formula:

    [H^+] = a * Molarity

    = 1 * 0.35 M

    = 0.35 M (the concentration of H^+)

    pH = - log [H^+]

    = - log 3.5*10^-1

    = 1 - log 3.5

    = 0.456

    The pH of the solution is 2.10.

    Explanation:

    The pH gives us an idea of the acidity or basicity of a solution. More precisely, it indicates the concentration of H30 + ions present in said solution. The pH scale ranges from 0 to 14: from 0 to 7 corresponds to acid solutions, 7 neutral solutions and between 7 and 14 basic solutions. It is calculated as:

    pH = - log (H30 + )

    pH = - log (0.0080)

    pH = 2.10
