A solution of acid was found to have a pH of 1.50. What is the hydrogen ion concentration of the solution? (Give your answer in scientific notation to 3 significant figures.)

  • maths - ,

    1.5 = - log H+
    10^1.5 = 1/H+
    H+ = 1/ 10^1.5 = .0316

  • maths - ,

    or 10^-1.5 = .0316
    or antilog (-1.5) = .0316

    lots of ways to do it, all really the same
