Which solution is used for the leaching of silver metal in the presence of air in the metallurgy of silver?

Which metal foils are used for wrapping chocolates?

Which method is used for obtaining high purity metals for semi conductor? Describe the process.

Write the reaction when silver is leached with KCN.

When electrolysis of silver nitrate solution is carried out using silver electrodes which of the following reaction occurs at the anode?

Select the correct answer : The metal which becomes black in the presence of H_2S gas is iron/silver.

Zinc and not Copper is used for the recovery of silver from the complex. [Ag(CN)_2] discuss.

One half-cell in a voltaic cell is constructed from a silver wire dipped in silver nitrate solution of unknonw concentration. It other half cell consists of a zinc electrode dipping in 1.0M solution of Zn(NO_3)_2 . A voltage of 1.48V is measure for this cell. Use this information to calculate the concentration of silver nitrate solution used (E_(Zn^(2+)//Zn)^0=-0.76V,E_(Ag^+//Ag)^0=+0.80V)

A brooch is made with silver wire in the form of a circle with diameter 35 mm.The wire is also used in making 5 diameter which divide the circle into 10 equal sectors as shown in Fig.12.12 .Find:(i)the total length of the silver wire required.

Two electrolytic cell containing AgNO_3 solution and dilute H_2SO_4 solution were connected in series. A steady current of 2.5 ampre was passed through them till 1.078g of silver was deposited. (Ag = 108 u, IF = 96500 C). How much electricity was consumed?

A blackish brown coloured solid 'A' when fused with alkali metal hydroxides in presence of air, produces a dark green coloured compound 'B' which on electrolytic oxidation in alkaline medium gives a dark purple coloured compound 'C' Identify A, B and C and write the reactions involved.
