Titration of acids and bases


titration of acids and bases

volume and the volume and concentration of the standardized titrant. Mole NaOH mean NaOH x volume NaOH used (5). Equivalence Point Indicators, before you begin the titration, you must choose a suitable pH indicator, preferably one that will experience a color change (known as the end point) close to the reactions equivalence point; this is the point at which equivalent amounts of the reactants. The NaOH solution was slowly dropped into the flask contained KHP solution for titration from the buret. An Indicator is sensitive to the medium it is in and is able to change colour accordingly. By definition, in an acid-base titration, the species involved are acids and bases. Weak acids are not often titrated against weak bases, however, because the color change is brief and therefore very difficult to observe. The mole of KHP was equal to the mole of NaOH based on the balanced chemical equation (1 since the ratio is 1:1. The amount of NaOH solution used to titrate was about.023 L per.49g KHP.

(CC.0) via Commons Iodometric titration mixture by LHcheM Own work. Main Difference Acid-Base Titration vs Redox Titration. The mole of KHP was calculated by dividing the mass of KHP used in each trial to the molar mass of KHP.

Also, there could be loss in the amount of KHP when transferred to the flask after weighed. The reaction that occurs between the two species is trickled down to the reaction between H ions and OH- ions. (CC BY-SA.0 ) via Commons. Place an accurately measured volume of the analyte into the Erlenmeyer flask using the pipette, along with a few dolphins or Patriots drops of indicator. However, end point os the actual point that is reached in neutralization reaction. This lets us quantitatively analyze the concentration of the unknown solution. Place the standardized solution into the burette, and indicate its initial volume in a lab notebook. The two main types of titrations are acid-base titration and redox titration. And when a species get reduced, it accepts electrons, and its oxidation number decreases. Record the initial and final readings on the burette, prior to starting the titration and at the end point, respectively.
