Titration is a fundamental analytical chemistry technique used to measure the concentration of an unknown solute in a solution. It involves adding a titrant of known concentration to an analyte until the reaction is complete, indicated by a color change or electrical measurement. The process is crucial for quantitative analysis in research, industry, and education, with applications in inorganic chemistry, environmental monitoring, and pharmaceuticals. Understanding the titration curve and equivalence point is essential for accurate analysis.
