What are Chromophore? Although the absorption of ultraviolet radiation results from the excitation of electrons from the ground to excited states, the nuclei that the electrons hold together in bonds play an important role in determining which wavelengths of radiation are absorbed. The nuclei determine the strength with which the electrons are bound and thus … Read more
Limit test for chlorides, sulphates, lead, iron, heavy metals and arsenic are official tests designed and mentioned in the individual monograph of pharmaceutical substance in Indian Pharmacopoeia. The limit of impurity is provided in terms of parts per million(ppm).
Polarography is the branch of voltammetry in which a dropping mercury electrode is used as the indicator electrode. It is the technique that deals with the effect of the potential of an electrode on the current that flows through it. The electrode whose potential is varied is called the indicator electrode.

Redox titration is used to determine the oxidizing agent or reducing agent in a solution. In a redox titration, either the reducing or oxidizing agent will be used as the titrant against the other agent.
Polarography is a type of voltammetry where the working electrode is a dropping mercury electrode (DME) or a static mercury drop electrode (SMDE), which are useful for their wide cathodic ranges and renewable surfaces.
MCQs in Complexometry and Precipitation titrations
Complexometric Titration is a type of analysis in which the formation of a coloured complex is used to indicate the end point of a titration. Complexometric titrations are particularly useful for the determination of a mixture of different metal ions in solution. Read further details in the file given below Complexometry
GRAVIMETRY Gravimetric methods are quantitative methods that are based on measuring the mass of a pure compound to which the sample is chemically related. Since weight can be measured with greater accuracy than almost any other fundamental property, gravimetric analysis is one of the most accurate classes of analytical methods.
