The pH of 0.100 M succinic acid needs to be calculated assuming H 3 O+ produced in the ionization step only and assuming some possibility that H 3 O+ produced in second ionization step as well. The two values need to be compared. Concept introduction: The pH of the solution used to measure the molar concentration of hydrogen ion in the solution and it is the measure of basicity or acidity of a solution. For any solution, if pH is less than 7 then it is acidic, pH equal to 7 is neutral and solution having pH greater than 7 is basic. In an acidic solution, the concentration of hydrogen ion is greater than hydroxide ion.
