Redox indicators: Characteristic, Types, Examples

Redox indicators

Redox indicator is an organic compound that exhibit a change in color in both the reduced and oxidized states, or at various potential values. Depending on oxidation and reduction potential, these organic molecules undergo structural change during redox titration. In oxidation … Read more

Fajan rules: Covalecy in ionic compounds

Fajan's rules

 Fajan’s rules can be used to determine the tendency of ionic compounds to acquire covalent character as a result of polarization. K. Fajan studied the factors which introduced the covalent character in the ionic compounds and purposed a set of … Read more

Unimolecular Elimination Reaction (E1 reaction)

Unimolecular elimination reaction (E1 reaction)

An unimolecular elimination reaction is referred to as an E1 reaction. It is a close analog to the SN1 reaction and the opposite of the electrophilic addition reaction. It is a two-step reaction that typically involves tertiary alkyl halides, though … Read more

Qualitative Salt Analysis: Common Ion Effect

Qualitative salt analysis

Qualitative salt analysis is the process of determining the number of constituents present in an unknown salt sample. The common ion effect is most commonly used in the salt analysis, i.e. qualitative analysis of basic radicals (in group separation). In qualitative … Read more

Common ion effect: Important Applications

Common ion effect

Common ion effect refers to the suppression of a weak electrolyte’s degree of ionization by the addition of a strong electrolyte that shares one ion with it.   Therefore, the common ion effect is used whenever it is necessary to prevent the … Read more
