    Please walk me through the calculation of determining how much NaOH is needed to raise a 1 liter solution of acetic acid and water with a pH of 4.5 to a final pH of 6.0 ---- this would be at 25 degrees C? What happens in this system if temperature is 55 degrees C?

    These are really tough questions, although they seem simple when one first reads them.

    This would qualify as a buffer question however...it starts out as a weak acid problem.

    When you are calculating the pH of a weak acid one usually uses the:

    Ka = x^2/C-x generic equation, where Ka is the acid dissociation constant, C is the concentration of the acid, and x represents both the hydrogen ion concentration[H+] and the concentration of the ...

    Solution Summary

    The solution determines the amount of NaOH required to raise acetic acid solution and water pH from 4.5 to 6.0.
