Experiment 18
Activity series of metals
Purpose: to introduce observation of the reaction, to write equations, balance them and to determine the relative bodily process of a metal.
Equipment
1. Test tubes
2. Zinc metal
3. Copper metal
4. Iron Metal
5. magnesium metal
6. Solutions
Procedure
1. Obtain 2 clean test tubes and pour 2 ml of each solution. Add a piece of surface metal to each solution. If there isnt a conterminous reaction allow the test tubes to stand for some minutes. go into your observations.
2. Repeat the step above for each metal. After do with the experiment clean each test tube well between each set of reactions.
Metal| Solutions|
| ZnCl2| CuCl2| Fecl3| MgCl2| HCL|
Zn| | R; Turned Darker in color| R; Started bubbling| NR| R; Started bubbling and the test tube god foggy|
Cu| NR| | NR| NR| NR|
Fe | NR| R; Iron turned a copper colored color| | No Reaction| R; Started Bubbling|
Mg| R; Started Bubbling| R; Started Bubbling| R; meagerly Bubbled| | R; Started bubbling, the Mg turned white and dissolved |
determination:
1. Mg
2. Zn
3. Fe
4. Cu
