Titration Essay example: Introduction A titration is a laboratory procedure involving the carefully measured and controlled addition of a solution from a buret into a measured volume of a sample solution. By definition, volumetric analysis is quantitative analysis using accurately measured titrated volumes of standard chemical solutions. Titration is an example of volumetric analysis because it involves accurately measured volumes of a sample solution for analysis. The type of titration carried out is acid base titration using HCl and Na2CO3. In this titration, three major steps involved were first measure out an amount of known solution, add indicator and three, to titrate using unknown solution. At the first colour change the titration would stop. Abstract The purpose to this lab is to standardize an approximately 1 mol•L-1 solution of hydrochloric acid. There were many steps taken in this titration but the main steps were measuring out the amount of known solution, adding the indicator and finally, titrating the solution until the first colour change. In each trial, the initial reading, final reading and the volume of HCl used was recorded down as quantitative results. The average volume of hydrochloric acid was found to be 12.03mL. The amount of sodium carbonate in the 10.00ml of solution was found to b 0.05 mol. The amount of hydrogen chloride that was dissolved in the average volume of acid is 0.365g. Through these calculations, the concentration of hydrochloric acid was found to be 8.3 mol•L-1.
