Interpretation: Types of battery and it uses.
Conceptual Introduction: There are two types of battery:
a) Primary battery: Once discharge then cannot be reused again. Example: alkanline battery, mercury battery, silver oxide battery and zinc oxide battery.
b) Secondary Battery: Can be charged again and again. These batteries are reusable.Example: lead acid battery, lithium battery.
Solutions: The batteries are used according to the requirement of the individual.If high amount of current is required we us lithium or silver oxide batteries. But silver oxide battery are expensive this made it uses little lesser. Alkaline battery are used in remote, toys, MP3 as these have long life span, works even at low temperature.

- Electrochemical Cells II Consider this cell running under standard conditions: Ni(s)Ni2(aq)Cu+(aq)Cu(s) a Is this cell a voltaic or an electrolytic cell? How do you know? b Does current flow in this cell spontaneously? c What is the maximum cell potential for this cell? d Say the cell is connected to a voltmeter. Describe what you might see for an initial voltage and what voltage changes, if any, you would observe as time went by. e What is the free energy of this cell when it is first constructed? f Does the free energy of the cell change over time as the cell runs? If so, how does it change?arrow_forwardThe mass of three different metal electrodes, each from a different galvanic cell, were determined before and after the current generated by the oxidation-reduction reaction in each cell was allowed to flow for a few minutes. The first metal electrode, given the label A, was found to have increased in mass; the second metal electrode, given the label B, did not change in mass; and the third metal electrode, given the label C, was found to have lost mass. Make an educated guess as to which electrodes were active and which were inert electrodes, and which were anode(s) and which were the cathode(s).arrow_forwardConsider the following cell running under standard conditions: Fe(s)Fe2+(aq)Al3+(aq)Al(s) a Is this a voltaic cell? b Which species is being reduced during the chemical reaction? c Which species is the oxidizing agent? d What happens to the concentration of Fe3+(aq) as the reaction proceeds? e How does the mass of Al(s) change as the reaction proceeds?arrow_forward
