Acid-base chemistry is a fundamental concept in chemistry, and understanding it is crucial for success in both high school and university-level chemistry courses.
Acids and bases have been explained by various definitions over the years. The most regarded ones are made by Arrhenius and Brønsted-Lowry. Acids and bases are labeled weak or strong based on the extent of ionization. Strong acids and strong bases ionize completely in an aqueous solution to generate very weak conjugate bases and very weak conjugate acids, respectively. Weak acids and bases ionize only partially in aqueous medium. To indicate the acid and base strength of a solution pH, which is a number usually between 0 and 14, pH meters or universal indicators are used.
Titration is a volumetric analysis method used to find the concentration of acid or base. The solution of unknown concentration is called an analyte. This method can be applied utilizing various acid-base indicators or a pH meter. In the case of acid-base titrations with a pH meter, equivalence points are important. The equivalence point is the theoretical titration point where the mole number of the acid is equal to the mole number of the base. The equivalence point is found in the graph created with the values read from the pH meter. In the case of acid-base titrations with indicators, the endpoint should be close to the equivalence point. The Endpoint is reached when the indicator changes the color of the solution.
