One of the discussion of important chemical reactions is kimia.Reaksi Chemistry is the process of change of a chemical compound (reactants) into other chemical compounds (products). When there is a chemical reaction, we will never get to see the inception of a new compound by naked eye.



The characteristics of chemical reactions
But in this process are the characteristics of a chemical reaction has occurred. There are ten different signs that characterize the chemical change in a substance:
The characteristics of occurrence of Chemical Reactions

1. The formation of gas bubbles.

Gas produced in a chemical reaction sometimes causes the formation of bubbles.
Bubbles can arise from heating a liquid or gas formation in the liquid. Both of these events is a common chemical reactions occur.
2. Establishment Deposition.

When mixing the two substances that are soluble in the solvent, then formed solids at the bottom of the solution, indicating the occurrence of chemical reactions in the solution.
The formation of this precipitate sometimes in the form of very small particles (micro) floating in solution so it is not visible. To make sure you can meyenterkan light on the solution. This phenomenon is known as the Securities Brown (Brown Effect)
3. The occurrence of Color Changes.

Some chemical compounds have a tendency to absorb and emit colors. The ability to absorb and emit very specific color for some substances. So when there is a change (conversion) substances of reactants into products (new compound) there will be a color change.
It could be from two reactants colorless will produce colored compounds, or of colored reactants to form a colorless product. This incident shows the change of chemical (Chemical Reaction).
4. Temperature Change.

Every chemical compound has the energy. This energy is the energy in the chemical bonds within a compound. Break the bond requires energy, while the formation of chemical bonds release energy.
When the chemical reactions that occur melibatakan more than the formation of chemical bonds breaking chemical bonds, it would be excessive and the energy is released as heat and the temperature rises.
However, if a chemical reaction involving more break the bond than the bond formation, it will be less and the energy absorbed from the environment led to the cold and decreasing temperature.
5. Transmitting light.

Chemical reactions occasionally releases energy in the form of light. Examples of this chemical reaction is that the fireflies emit light when night.
6. Volume Changes occurred.

When a new compound (product) is formed, then the reactants compound will be reduced drastically. The formation of new compounds and the reduction of these reactants can cause drastic changes in density so that the volume change.
7. Changes in conductivity.

Some chemical reactions produce or modify ion daapat into other compounds. This will affect the change in conductivity of a system.
8. There is a change Bau.

Some chemical compounds (such as ammonia) have strong odors. Hence the formation of ammonia or other smelling compounds will cause changes in odor on the system.
9. Changes in Taste.

Chemical compounds that have a particular flavor will result in change in taste when it reacts. This can be easily observed when we boil the potatoes, initially not too sweet potato flavor, then boiled glucose will be formed which has a sweet taste.
10. There is a change Boiling and Freezing Point.

Generally this happens in the crystal. To find a crystal has reacted or not, can use the boiling point and freezing point.
That's 10 Characteristics of chemical reactions that have occurred in a system.
