Titration is the controlled mixing of a solution with known concentration (the standard solution) to another solution to determine its concentration one solution is acidic and the other is basic an indicator is added to the mixture. Quantitative chemistry titration acid-base (simple) making a standard solution titration acid-base titration – redox titration – precipitation aim. Neutralization titrations standard solutions of strong acids and bases are widely used for determinations involving analytes that are acidic or basic or can be made so standard solutions the standard solutions used in neutralization titrations are strong acids or bases for complete reaction and sharper end points.
How can the answer be improved. There are many types of titration when considering the goals and procedures but, the most common types of titration are redox titration and acid-base titration. Titration is the slow addition of one solution of a known concentration (called a titrant) to a known volume of another solution of unknown concentration until the reaction reaches neutralization, which is often indicated by a color change.
