WebThe concentration of an acid solution can be determined by titration with a strong base. First, calculate the number of moles of strong base required to reach the equivalence point of the titration. Then, using the mole ratio from the balanced neutralization equation, convert from moles of strong base to moles of acid. WebIn calculating pH of NaOH solution, first, we have to calculate the pOH value. We have a relationship between pH and pOH as below. pH + pOH = pKa pKa is a constant to a certain temperature and pKa = 14 at 25 0 C. So at 25 0 C, pH + pOH = 14 Methods to use for calculating pH of a base We can use two methods to calculate pH of basic solution. chiropractic school in laWebApr 29, 2014 · NaOH is a strong base, so this will produce 0.1mol/L of OH ions in solution.
