How many grams of NaOH should be dissolved in 1 litre of solution to prepare a solution with pH value12

  • chemistry - ,

    pH = 12
    pOH = 14-12 = 2
    OH^- = 1 x 10^-2
    Therefore, (NaOH) = 1 x 10^-2 M - 0.01 moles/L
    moles = grams/molar mass. You know moles and molar mass, calculate grams.
