Introduction
A titration is a laboratory turn involving the carefully measurementd and controlled addition of a ascendent from a buret into a measured stack of a specimen solution. By definition, volumetrical analysis is quantitative analysis development accurately measured measured 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 sum up of known solution, add indicator and three, to titrate using unknown solution. At the first colour transfer the titration would stop.
Abstract
The purpose to this lab is to standardize an approximately 1 moleL-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 utilise 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 total heat chloride that was dissolved in the average volume of acid is 0.365g. by dint of these calculations, the concentration of hydrochloric acid was found to be 8.3 molL-1.
