Calculate the concentrations of hydronium and hydroxide ions in a solution prepared by dissolving 0.345g of solid NaOH in enough water to make 225mL of solution. Also calculate the pH and pOH of the solution.

  • Chem I -

    NaOH is a strong electrolyte. It ionizes completely.
    moles = grams/molar mass.
    Solve for moles.

    M = moles/L soln.
    Substitute and solve for OH, convert to pOH, then to pH.

    Thank you! I will probably have more questions in a bit! I appreciate it!
