aqueous reactions and solution stoichiometry

Redox Reactions in Aqueous Solution - Redox reactions in aqueous solution can be classified into the following two typ..

Direct Redox Reaction When the reacting species, capable of losing electrons (reducing agent) and that capable of gaining electrons (oxidizing agent) are present in the same solution a direct redox reaction takes place. In direct redox reactions,..

(due to its highly negative electrode potential). Instead, H + ions produced due to the self-ionization of water get reduced at cathod..

Solutions that contain water as the solvent are called aqueous solutions. For example, sugar in water, carbon dioxide in water, e..

In the electrolysis of aqueous copper sulphate between copper electrodes the anode is made up of a thick block of impure copper, and the cathode is made up of a thin sheet of pure copper (Fig.4.11). The reactions that take place ar..

The quantitative relationships between different species in the redox reactions gives its stoichiometry. These relationships are derived in the same manner as derived for general chemical equations after writing the balanced redox equati..

A chemical reaction can be represented by a chemical equation, which may be defined as a chemical change in terms of symbols and formulae of the substances involved in the reaction. The substances that react among themselves to bring about the chemical changes are known as react..

Solutions that contain a solvent other than water are called non-aqueous solutions. Ether, benzene, petrol, carbon tetrachloride etc., are some common solvents. For example: sulphur in carbon disulphide, naphthalene in benzene, e..

When ammonia is passed through aqueous solutions of certain salts, the respective metallic hydroxides are precipitated. In the case of salts of copper, the blue precipitate of copper hydroxide formed dissolves in excess of ammonia solution to give a deep b..
