acid base titrations calculations

Acid Base Titrations - In acid base titrations, a base is added to an acid successively (or vice versa) and the pH of the solution is noted after every addition. The plot of pH against the amount of base (or h..

In acid base titrations, a base is added to an acid successively (or vice versa) and the pH of the solution is noted after every addition. The plot of pH against the amount of base (or acid) added is called a titration..

Titration is an operation for the measurement of quantities of substances in solution by the method of 'volume analysis'. This process involves adding a solution of the reagent of known concentration (standard solution), taken in a burette (called 'titrant'), to an unknown solution ..

This type of titration is carried out between a weak acid such as acetic acid (CH 3 COOH) and weak base such as ammonium hydroxide (NH 4 OH). There is no sharp change in the pH during the titration. Hence, no sharp equivalence point can be obtain..

When we add a solution of NaOH to the solution of HCl, the pH progressively increases. This is because OH - ions from the base will react with H + ions of the acid to form water. This decreases the concentration of H + ions and therefore pH increases. The pH of the solutio..

Let, The mass of the acid dissolved be = W g Volume of alkali used for complete neutralization of acid solution = V 1 mL Normality of the alkali solution = N 1 Then, we can write, V 1 mL of alkali solution having normality N 1 = Wg acid From the definition, 100..

The amount of an acid (or a base), which is exactly equivalent chemically to the amount of some standard base (or an acid), is determined by an acid-base titration. The point of equivalence is called end point. The solution of a strong ..

Let, Mass of the organic compound = W g Volume of the standard acid required for complete neutralization of the evolved ammonia = V mL Normality of the standard solution of acid = N From the law of equivalence (normality equation), 1000 mL of 1 N acid = 1000 mL of 1 N..
