What is a salt bridge?
Salt bridge is a device used to link two electrodes on electrochemical cell. It maintains electrical neutrality and internal continuity. It is shown by two vertical lines separating two half cells. A salt bridge is constructed by ?lling a U shaped glass tube with saturated Potassium Chloride solution mixed with agar-agar jelly and solidifying the contents by cooling.
Electromeric effect (1) The occurrence of movement of electrons from one atom to other in multi bonded atoms at the demand of attacking reagent is known as electromeric effect.
Half life of reaction refers to as the time during which the concentration of the reactants is reduced to half of the initial concentration or it is the time essential for the comp
The electronic configuration of silver atom in ground state is: (1) [ Kr]3 d 10 4 s 1 (2) [Xe]4f 14 5d 10 6s 1 (3) [ Kr]4d 10 5 s
Charactaristics of elements of group
Mesomeric forms are the possible locations of electrons at a single instant, if you get what I mean. Like, an adjacent double and single bond in a molecule. The resonance form, how
It can be because these group tend to decrease the electron density when attached to a benzene or other ring structure preferentially at ortho and pera position.
