Concept Introduction:
Redox reactions are the reactions in which both oxidation and reduction takes place simultaneously. Oxidation is the removal electron from an atom or ion. Oxidation process increases the oxidation number. Reduction is the addition of electron to an atom or ion. Reduction process decreases the oxidation number. The
Mole is the mass of the substance that is having
Molar concentration or molarity is the ratio of number of moles of solute to the volume of the solution in litre.

- An 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_forwardAlthough there are a number of magnesium-containing minerals, the commercial source of this metal is seawater. Treatment of seawater with Ca(OH)2 gives insoluble Mg(OH)2. This reacts with HCI to produce MgCl2, which is dried, and the metal is obtained by electrolysis of the molten salt. Write balanced net ionic equations for the three reactions described here.arrow_forwardOrder the following oxidizing agents by increasing strength under standard-state conditions: O2(g); MnO4(aq); NO3 (aq) (in acidic solution ).arrow_forward
- A galvanic cell is based on the following half-reactions: In this cell, the copper compartment contains a copper electrode and [Cu2+] = 1.00 M, and the vanadium compartment contains a vanadium electrode and V2+ at an unknown concentration. The compartment containing the vanadium (1.00 L of solution) was titrated with 0.0800 M H2EDTA2, resulting in the reaction H2EDTA2(aq)+V2+(aq)VEDTA2(aq)+2H+(aq)K=? The potential of the cell was monitored to determine the stoichiometric point for the process, which occurred at a volume of 500.0 mL H2EDTA2 solution added. At the stoichiometric point, was observed to be 1 .98 V. The solution was buffered at a pH of 10.00. a. Calculate before the titration was carried out. b.
