Summary Introduction

To explain: The important role buffers play in organisms.

Introduction: Substances have different properties due to their varying chemical nature. On the basis of chemical nature, substances are categorized as acidic, basic, or neutral. The pH is defined as the negative logarithm of hydrogen ion concentration of a solution which is expressed in moles per liter. The neutral solutions have same concentration of H+ and OH-. The neutral solution (10-7 mol/L) has a pH of seven. The pH value of base (alkali) is greater than 7. The pH value of acid is less than 7.
