Concept explainers
(a)
Interpretation:
A complete diagram of the galvanic cell has to be given.
Concept introduction:
Voltaic cell (or) galvanic cell:
Voltaic cell is an experimental setup used to generate
(b)
Interpretation:
The cathode and anode has to be labelled and the direction of flow of ions has to be indicated.
Concept introduction:
Voltaic cell (or) galvanic cell:
Voltaic cell is an experimental setup used to generate electric current through the spontaneous redox reaction. The voltaic cell is an electrochemical cell, which is converting a chemical energy into electrical energy. Cathode as the positive electrode. Anode as the negative electrode. Salt bridge is required. Ions are discharged only in cathode while anode is consumed.
(c)
Interpretation:
The balanced cell reaction has to be given.
(d)
Interpretation:
The shorthand notation has to be given.
Cell notation:
The shortest way for representing a certain electrochemical reaction is called as cell notation. The cathode and anode are separated through two bars or slashes representing a salt bridge, with anode present in the left and the cathode present on the right. Single bar is used to separate an individual solid, liquid or aqueous phases with each half-cell.

- The following two half-reactions arc involved in a voltaic cell. At standard conditions, what species is produced at each electrode? Ag++eAgE=0.80VNi2++2eNiE=0.25Varrow_forwardA potassium chloride solution is electrolyzed by passing a current through the solution using inert electrodes. A gas evolves at each electrode, and there is a large increase in pH of the solution. Write the half-reactions that occur at the anode and at the cathode.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_forward
- Give the notation for a voltaic cell whose overall cell reaction is Mg(s)+2Ag+(aq)Mg2+(aq)+2Ag(s) What are the half-cell reactions? Label them as anode or cathode reactions. What is the standard cell potential of this cell?arrow_forwardAn electrode is prepared from liquid mercury in contact with a saturated solution of mercury(I) chloride, Hg2Cl, containing 1.00 M Cl . The cell potential of the voltaic cell constructed by connecting this electrode as the cathode to the standard hydrogen half-cell as the anode is 0.268 V. What is the solubility product of mercury(I) chloride?arrow_forward
