    Galvanic cell: A galvanic cell is an electrochemical cell that converts the chemical energy of a spontaneous redox reaction into electrical energy. In this device, the Gibbs energy of the spontaneous redox reaction is converted into electrical work which may be used for running motor or other electrical gadgets like heater, fan, geyser, etc.

    The anode is the electrode where oxidation (loss of electrons) takes place. The anode attracts anions. The cathode is the electrode where reduction (gain of electrons) takes place. The cathode attracts cations. But in electrochemistry➡ Anod is that terminal where oxidation occurs. Cathod is that terminal where reduction occurs.

    Anode (+ve charge) is connected with positive terminal. Cathode (-ve charge) is connected with negative terminal.

    <th scope="col">Electrochemical cell (Galvanic Cell)</th> <th scope="col">Electrolytic cell</th>
    A Galvanic cell converts chemical energy into electrical energy. An electrolytic cell converts electrical energy into chemical energy.
    Here, the redox reaction is spontaneous and is responsible for the production of electrical energy. The redox reaction is not spontaneous and electrical energy has to be supplied to initiate the reaction.
    The two half-cells are set up in different containers, being connected through the salt bridge or porous partition. Both the electrodes are placed in a same container in the solution of molten electrolyte.
    Here the anode is negative and cathode is the positive electrode. The reaction at the anode is oxidation and that at the cathode is reduction. Here, the anode is positive and cathode is the negative electrode. The reaction at the anode is oxidation and that at the cathode is reduction.
    The electrons are supplied by the species getting oxidized. They move from anode to the cathode in the external circuit. The external battery supplies the electrons. They enter through the cathode and come out through the anode.

    Dont try to mug up chemistry... try to understand it. If it is numerical- what all is given in question write it down separately and now war we should find check... and write its formula if again some given value is missing write that formula and try to find that. Inorganic understand why there is change in radius,physical properties think.... then find out the answer it will be remembered... organic u need to practice the equations all. Say it is easy it will bring confidence. If u say it is difficult it will be more difficult to study then..

    Typical reactions of benzene ring namely halogenation, nitration, sulphonation, and Friedel-Craft reaction are electrophilic substitutions.
    Benzene ring serves as a source of electrons (nucleophile) due to the presence of electron cloud. The electrophilic reagent will attack the aromatic nucleus and the hydrogen atom of benzene is displaced by the electrophilic reagent. A substituted product is formed via intermediate carbonium ion formation.

    • Sealing of soft drink bottles at high pressure increases the solubility of CO2 in soft drinks and soda water.
    • When a diver goes underwater his body is subjected to high pressure. Due to this the body tissues absorbs more gases. The breathed in oxygen is required for cellular respiration to provide energy to the diver. But the nitrogen gets absorbed into the body tissues.
    • At high heights the fractional weight of oxygen is not as much as that at the ground level. This stimulates low concentrations of oxygen in the blood and tissues of individuals living at high heights or climbers. Low blood oxygen causes climbers to feel feeble and not able to think plainly, indications of a condition known as anoxia.
