Some metals and salt solutionsaregiven `(Cu,Zn, Ag, ZnSO_4, AgNO_3, MgCI_2)`: Draw the diagram of a Galvanic cell that can be made using these substances.

You have used threee metals Zn, Cu and Ag. How many cells can be produced using these?

You are given a solution of AgNO_3 , a solution of MgSO_4 , a Ag rod and a Mg ribbon. How can you arrange a Galvanic cell using these? Write down the reactions taking place at the cathode and the anode.

Certain metals are given below. Ag,Zn,Pb,Sn,Fe: When a galvanic cell is constructed us-ing these metals, which one acts only as anode? Give the reason.

How many Galvanic cells can be made by using the metals Ag, Cu, Zn and Mg. When Galvanic cells are made using the metals given, what will be the nature of reactions in each cell? (Reactivity: Mg gt Zn gt Cu gt Ag).

Some metallic compounds /ores are given below [ZnS, .Al_2 O_3 .2 H_2 O, Cu_2 S] Make a table containing ores, concentration method of the ore, name of the metal and one alloy of the metal.

Some materials are given below: From the given materials, choose the appropriate ones to construct a galvanic cell and draw the diagram of the cell. (Order of reactivity: Mg>Fe>Cu>Ag)

The reactivity series of a few metals are given below. Mg gt Zn gt Fe gt Cu gt Ag a) What happens. ii) When a piece of silver is dipped in zinc sulphate (ZnSO_4) solution. b) If a galvanic cell is constructed using Fe and Ag electrodes which will be the positive electrode?

You are given conc. HCl and salts of some alkaline earth metals and directed to conduct flame test and to detect the cation present in each salt. (a) Can you detect all the cations which are given here by this method? [CaCl_2, MgSO_4, Ba(NO_3)_2, BeCl_2, SrCl_2] (b) Justify your answer. (c) What is the mechanism of this test?
