The technique for calculating the pH of a strong base in water, difficulty in calculation of pH of Ca(OH) 2 , pH of a weak base in water, ± 5 % rule failure alternative, element responsible for the basic properties is to be stated. Concept introduction: The pH of strong bases is calculated directly by finding out the major species. The pH of weak bases are calculated by considering the change in initial concentration at equilibrium. The ± 5 % rule is valid only when the difference between initial and equilibrium concentration is less than ± 5 % .
