PH scale is used to determine how acidic, basic or neutral a solution is. It can be calculated using the following equation

pH = - log [H₃O⁺]

hydronium ion concentration has already been given

[H₃O⁺] = 4.91 x 10⁻⁴ M

pH = - log[4.91 x 10⁻⁴ M]

pH = 3.3

the pH of medium is 3.3

If a sample of a certain solution is determined to have a [h3o+][h3o+] concentration of 4.91*10-44.91*10-4 moles/liter, what is its ph? round off your answer to one decimal place.
