Acid-Base Titration, Determination of Carbonate and Bicarbonate in a water sample. However, preparation of the report including data analysis, interpretation and discussion must be prepared by the individual student submitting the report. Filling the burette, measuring out the alkali into the flask, and titrating it until it is neutralised takes about 20 minutes, with false starts being likely for many groups. The peak of the derivate curve indicates the endpoint volumes. a. Complete your data table when you finished. In this experiment you will use the titration technique to determine the concentration of the provided sodium hydroxide solution. Titration - Lab Report Example. Chemistry 355 Section JW. This is a chemistry lab report on an Acid-Base Titration experiment. We can determine the concentration of the bases in … The point of chemical equivalence is indicated by a chemical indicator or an instrumental measurement. putting in the equations used into the data table. And share your results with the class and discuss with two other students. Introduction: The main objective of this experiment was to obtain the molar mass and pKa of a weak acid, then, use this information to identify the unknown acid. Other related documents. and add another 3 drops of phenolphthalein. The aim of this lab practical is to carry out the titration of a base, sodium hydroxide with two acids: firstly hydrochloric acid and then sulphuric acid so as to determine the molarities of the two acids. In the neutralization of hydrochloric acid by sodium hydroxide, the mole ratio of acid to base is 1:1. Titration Experiment. Potentiometric Titration. A titration is an experiment where a volume of a solution of known concentration is added to a volume of another solution in order to determine its concentration. Cite.

The two steps, (i) and (ii), are essentially similar. Then, the derivative of each curve was calculated and graphed. Other related documents. Find answers and explanations to over 1.2 million textbook exercises. Filling the burette, measuring out the alkali into the flask, and titrating it until it is neutralised takes about 20 minutes, with false starts being likely for many groups. Full Lab Report Experiment #2: Acid-Base Titration Lab Description: Acid-Base Titration Introduction In this lab exercise we will evaluate the effectiveness of several indicators for the determination of the point of completion of a specific acid-base neutralization reaction. We had a measurement at the end of the experiment of 20.2 mL NaOH, for a total of 10mL, or .01L of NaOH used. The Department does not tolerate plagiarized report! This preview shows page 1 - 2 out of 4 pages. 2714 Words | 11 Pages. The equivalence point is when the same number of moles of acid and moles of base has been added. First, the data from the experiment (the volume of the NaOH titrant added and the pH for each increment) was input into a software called Graphical Analysis. Do two trials of sample, You will use the volume you measured of the NaOH required to neutralize the HCl to determine the, You will need to convert mL to Liters for each substance and calculate. Repeat the same steps as trail 1. Lab report DETERMINATION OF CONCENTRATION OF ACETIC ACID IN VINEGAR. Determination of Na2CO3 in Soda Ash Conductimetric Titration & Gravimetric Determination of BaSO4 Lab Report Gas Laws Report. One type of titration uses a neutralization reaction, in which an acid and a base react to produce a salt and water: In equation 1, the acid is HCl (hydrochloric acid) and the base is NaOH (sodium hydroxide). Download. Introduction: A titration is a procedure in which two solutions are introduced to form a reaction that once completed, reaches an identifiable endpoint (Murphy, 2012, p.305). 2714 Words | 11 Pages. We started with the NaOH in the buret at 10.2mL. Therefore, only the first step is briefly described below. Ph electrode will be used in this experiment.
