Practical 5: Properties of Compound

Experiment 1: Homes of A Chemical substance and Its Father or mother Elements

Hypothesis

The hypothesis of this try things out is magnesium oxide could be synthesized by combining (burning) the magnesium with o2. The chemical substance and physical properties of each element (magnesium, oxygen, and magnesium oxide) might be diverse, from the express, color, electrical conductivity, and pH. Purpose

This try things out was performed to synthesize magnesium oxide by immediate combination of magnesium and fresh air and to compare the houses of the components (magnesium and oxygen) inside their elemental express with the properties of the mixture of these components (magnesium oxide). Introduction

When ever elements respond to form compounds, their chemical and physical properties transform. Their exterior shells become complete (the octet rule) and the resulting compound is often more steady. In this try things out, magnesium oxide will be synthesized by immediate combination of magnesium (mg) with fresh air. The houses of magnesium, oxygen, and magnesium o2 will be examined and compared. The balanced chemical equation for this process is: Mg + UNITED KINGDOM 2MgO

Components:

*

* Magnesium (mg) ribbon

5. H2O (water)

* Tongs

* two hundred fifty ml beaker

* Check tubes

5. 10 cubic centimeters measuring canister

* Bunsen burner

2. Safety eyeglasses

* Stir rod

2. Universal signal (include pH color chart)

* Electrolyte tester

* Stopper

Procedure

1 . Observed and record the state of hawaii, color, plus the electrical conductivity of the magnesium ribbon and record the result. 2 . Put 1 centimeter of magnesium ribbon to a beaker that was added with twelve ml of water (H2O) and added some drops of Universal Indicator (UI) into the test out tube. 3. Observe and record colour result and pH.

4. Added 10 ml of water and handful of drops of Universal Signal (UI) in the test conduit. 5. Stopper before shook the test conduit to fill the water (H2O) with the o2 (O2). 6th. Record colour result and pH.

7. Got a pair of tongs, snapped the magnesium bows, and burnt it in a Bunsen burner flame, after that moved the burning strip over a two hundred fifty ml beaker. After that, position the magnesium oxide (MgO) ashes into a beaker. On this stage, please utilized the safety glasses to avoid the permanent damage to our eyes and also usually do not looked straight at the burning up magnesium. eight. Observe and record the state of hawaii and color. Don't forgot to as well observe and record the electrical conductivity of the Magnesium (mg) Oxide (MgO) by using the electrolyte tester. being unfaithful. Added twelve ml of water and some drops of Universal Signal (UI) in the beaker, after that mixed with the stirring fly fishing rod. 10. Notice and record the result color and ph level.

Results

| Mg| O2| MgO

State| Solid| Gas| Solid

Color| Grey| Clear| Grey

Electric conductivity| High| non-e | None

Color of water mix added with Universal Signal (UI)| Dark green| Lumination Green| Light purple| ph level of drinking water mixture| 9| 7| 10

Analysis

Depending on the benefits, magnesium oxide can be synthesized by incorporating (burning) the magnesium with oxygen. The chemical and physical properties such as the express, color, electrical conductivity, and pH are very different for each factor, except for similar state among magnesium and magnesium o2 and the same electrical conductivity between fresh air and magnesium oxide. Discussion

The try things out was effectively done and support the hypothesis based on the reliability when the factors were being analyzed to learned some of the properties. Conclusion

The conclusion from the test is, magnesium (mg) oxide could be synthesized by combining magnesium and oxygen. From the combining or the losing itself, this produced some ashes that contained magnesium oxide, and became another express or improvements. The properties of the new substance, magnesium (mg) oxide, were also different from magnesium or air. The magnesium (mg) oxide did not had any electrical conductivity same just like oxygen, when magnesium got...
