Using this formula..

pH = -log(H^+)

find the pH
1.6 x 10^(-5)

  • Chem -

    You need to learn how to do this.
    Punch 1.6 x 10^-5 into your calculator.
    Hit the log button. You should get -4.79588 so the equation now looks like this.
    pH = -log(H^+)
    pH = -log(1.6 x 10^-5)
    pH = -(-4.79588)
    pH = 4.79588 which rounds to
    pH = 4.80
