Titration: The word titration comes from the Latin word "titulus", which means inscription or title. The French word title means rank. Therefore, Titration means the determination of concentration or rank of a solution with respect to water with a pH of 7. The standard solution is usually added from a graduated vessel called a burette. The process of adding standard solution until the reaction is just complete is termed as titration and the substance to be determined is said to be titrated. All chemical reactions cannot be considered as titrations. A reaction can serve as a basis of a titration procedure only if the following conditions are satisfied: The reaction must be a fast one. It must proceed stoichiometrically. The change…show more content…
The reaction of the concentration of A & B leads to the reduction of the total free energy change. If the concentrations of A & B are too low the magnitude of the total free energy change becomes so small and the use of the reaction for titration will not be feasible. Expressions of Concentration of Solutions: The concentration or strength of solution means the amount of solute present in a given amount of the solution. The concentration may be expressed in physical or chemical units. Normality (N): It is defined as number of gram equivalents of the solute present in 1 liter (1000mL.) of the solution. If W g of solute of equivalent weight E is present in V mL of the solution, the normality of the solution is given by: Molarity (M): It is defined as the number of moles of the solute present in 1 liter (or 1000 mL) of the solution. A one molar solution contains 1 mole of the solute dissolved in 1 liter of the solution. Molality (m): It is defined as the number of moles of solute dissolved in 1000 g of the solvent. One molal solution contains one mole of the solute dissolved in 1000 g of the…show more content…
A measured volume of the solution of a substance A is allowed to react completely with the solution of definite strength of another substance B. The volume of B is noted. Thus we know the volume of the solutions A and B used in the reaction and the strength of solution B; so the strength of the other solution A is obtained. The amount (or concentration) of the dissolved substance in volumetric analysis is usually expressed in terms of normality. The weight in grams of the substance per liter of the solution is related to normality of the solution as, Weight of the substance (g per liter) = Normality × gram equivalent weight of the substance. Conditions of Volumetric Analysis: The reaction between the titrant and titrate must be expressed. The reaction should be practically instantaneous. There must be a marked change in some physical or chemical property of the solution at the endpoint. An indicator should be available which should sharply define the end point. In this experiment I’ll be looking at five different varieties of carbonated drinks they are Coca Cola, Sprite, Schweppes Ginger Ale, Fanta and Soda

    Indicators An indicator is a substance which is used to determine the end point in a titration. In acid-base titrations, organic substances (weak acids or weak bases) are generally used as indicators. They change their colour within a certain pH range. The colour change and the pH range of some common indica­tors are tabulated below: Indicator pH Range Over Which Colour Change Occurs Colour of Acidi Form Colour of Base Form Methyl Orange 3.2-4.5 Orange Yellow Methyl Red 4.4 – 6.5 Red Yellow
