Lab 2 – Titration 1 Titration allows the quantitative determination of one compound’s concentration by reaction with a precisely known quantity of a second reagent The titration reaction must go essentially to completion when forming products Most common titrations are performed with solutions because liquid volumes are easy to measure with high precision and accuracy/because solutions tend to mix rapidly and form homogenous products Lab process: determine the concentration of an NaOH solution by titrating it with a known mass of the compound potassium hydrogen phthalate (KHP), which as a single acidic proton which reacts with the OH ion rapidly and quantitatively o KHP can be weighed and used in ti
