Replacement Reaction of Tin and Zinc

 

Hazards: 

Solutions containing 3M HCl are corrosive and toxic.

Chemicals and Solutions: 

0.5M Tin (II) chloride

Zinc metal

Materials: 

Procedure: 

Place the zinc in the stannous chloride solution.  Tin will be plated out.  (The presence of acid in the solution means that hydrogen gas will also be formed).

Hint: 

tin (II) chloride solution (0.5M)

Dissolve 112.5 g SnCl2.2H2O in 1 L of 3M HCl

Discussion: 

SnCl2(aq) + Zn(s) ---> ZnCl2(aq) + Sn(s)

Zn(s) + 2HCl(aq) ---> H2 (g) + ZnCl2(aq)
