This video tutorial covers the basics of titration, a technique used to determine the unknown concentration of a solution by adding a titrant of known concentration until a color change indicates the equivalence point. It explains the differences in titration curves for strong and weak acids and bases, the importance of choosing the right indicator, and the unique characteristics of polyprotic acid titrations.
