Webb19 aug. 2024 · A student was titrating 25.00 mL of a basic solution with an HCl solution that was 0.281 M. The student ran out of the HCl solution after having added 32.46 mL, so she borrowed an HCl solution that was labeled as 0.317 M. An additional 11.5 mL of the second solution was needed to complete the titration.

The … WebbAs seen in the chapter on the stoichiometry of chemical reactions, titrations can be used to quantitatively analyze solutions for their acid or base concentrations. In this section, we will explore the underlying chemical equilibria that make acid-base titrimetry a useful analytical technique. Titration Curves WebbIn Titrimetric analysis, the one with known concentration is referred to as the titrant. While on the other hand, the substance being titrated is called the titrand or titer, or analyte. The point at which the reaction involved in titration between titrant and analyte completes the equivalence point or theoretical endpoint. shubham music
