acid base titrations titrant

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..

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 ..

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..

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 ..

Accordingly, carboxylic acids evolve hydrogen with electropositive metals as alcohols do. Carboxylic acids react with weaker bases such as carbonates and bicarbonates to evolve CO 2..

Modern Concept of Acid and Base - When acids combine with bases, acids give hydrogen ions to the base, and the base accepts them. We have already seen that a hydrogen ion is a proton. So when acid gives away a hydrogen ..
