Titration is an experimental technique that allows us to know the concentration of an unknown acid or base. ; 01:06 Why does heating the mixture help? Practical activity - carrying out a titration Titration. Titration is a general class of experiment where a known property of one solution is used to infer an unknown property of another solution. 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. Titration is the slow addition of one solution of a known concentration (called a titrant) to a known volume of another solution of unknown concentration until the reaction reaches neutralization, which is often indicated by a color change. In a titration, one reagent has a known concentration or amount, while the other reagent has an unknown concentration or amount. Module 9 : Experiments in Chemistry Lecture 38 : Titrations : Acid-Base, Redox and Complexometric Objectives In this lecture you will learn the techniques to do following Determination of the amount of sodium carbonate and sodium hydroxide in a mixture by titration. Fill the canister with warm water and then quickly put the cap on and watch the acid-base reaction! Titration is the process in which one solution is added to another solution such that it reacts under conditions in which the added volume may be accurately measured. First, convert the volume of acid used (25mL) to liters by dividing by 1000. Categories: Chemistry Laboratory. The substance has the formula C8H5K04, but because it behaves as a monoprotic… Ascorbic acid is suggested as the weighable compound for the standardization of iodine solutions in an analytical experiment in general chemistry.
