Finding out how much acid there is in a solution Aim: To determine the concentration of sulphuric acid by acid-base titration. Introduction: A titration is a procedure used in analytical chemistry to determine the amount or concentration of a substance. Analytical chemistry involves the study of chemical substances usually by experiments. There are two branches of the analytical chemistry: 1- Quantitative chemical analysis: concerned with the determination of the quantitative composition of pure compounds, mixtures and solutions. 2- Qualitative chemical analysis: involves deducing what substances are present. Methods of quantitative analysis are: 1- Volumetric (titrimetric) analysis. 2- Gravimetric analysis 3- Mass spectrometry Volumetric analysis It is used for to find the concentration of solutions by a technique know as titration. There are various types of titrations: 1- A cid-base titration. 2- Conductimetric titration, 3- Potentiometric titration. The principles of titration involve peppitting a portion (know as an aliquot) of the solution of unknown concentration (the titrate) into a conical flask. The...
