In acid-base titration react rapidly to neutralise each other. Equivalence point is a point at which the acid and the base (or oxidising agent and reducing agent) have beem added in equivalent quantities. The end point in the point at which the titration stops. since the purpose of the indicator is to stop the titration close to the point at which the acid and base were added in equivalent quantities, it is important that the equivalent point and the end point be as close as must change colour at a pH close to that of a solution of the salt of the acid base. Singificantly, the pH changes most rapidly near the equivalent point. The exact shape of a titration curve depends on K_(a) and K_(b) of acid and base. The pH at equivalence point is

Iodine titration can be iodemotric or iodimetric depending on using iodine directly or indirectly is an oxidising agent in the redox titration. a. Iodimetric titration in which a standard iodine solution is used as an oxidant and iodine is directly or indirectly titrated against a reducing agent. For example. 2CuSO_(4)+4KJtoCu_(2)I_(2)+2K_(2)SO_(4)+I_(2) b. Iodimetric procedures are used for the datermination of strength of reducing agent such as thiosulphates, sulphites, arsenties adn stanous chloride etc. by titrating them against standard solution of iodine in a burette. 2Na_(2)SO_(3)to2 NaI +Na_(2)S_(4)O_(6) Starch is used as indicator near the end point whilch form blue colour complex with I_(3)^(-) . The blue colour disappeams when there is not more of free I_(2) . When 319.0 gm of CuSO_(4) in a solution is related with excess of 0.5 M KI solution, then librated iodine required 200 ml of 1.0M Na_(2)S_(2)O_(3) for complete relation. The percentage purity of CuSO_(4) in the sample is

KMnO_4 is prepared from the mineral pyrolusite, MnO_2 (deep purple colour). It acts as an oxidising agent in the neutral, alkaline as well as acidic medium in acidic medium it is used in volumetric analysis for estimation of Fe^(2+) , Cr_2O_4^(2-) salts etc. The titrations are carried out in presence of H_2SO_4 . However, before using it as a titrant, it is first standardised with standard oxalic acid solution or Mohr's salt solution . In one of the experiments on titration 26.8g of dry pure sodium oxalate (Mw=123gmol^-1) was dissolved in 1L of distilled water and then 100 mL of 2MH_2SO_4 were added. The solution was cooled.
