Abstract
Analytical chemistry plays a major role in the quality control of various industrial chemical products. The quality and purity of the products are calculated and confined by applying various principles of chemistry. Thus analytical procedures are regarded to be the outcome of the fundamental principles of chemistry and related sciences. Neutralization titrations are common in establishing the quality of various industrial products taking account of the fact that industrial chemicals and products are mainly acids or bases. The results for the titrations performed on sample require sharp and distinct equivalence points that are identified by the use of suitable acidbase indicators. The present work is a review on common pH indicators used for the neutralization titrations in analytical chemistry.
