EXPERIMENT NO. 3

CLASSIFICATION OF MATTER 

OBJECTIVES

1. To differentiate an element from a compound

2. To identify an electrolyte and a non-electrolyte

3. To examine the color reactions of different acids and bases to different indicators

4. To define neutralization

5  To prepare ferric oxide sol, sulfur sol, and coconut oil-water emulsion

6. To illustrate Tyndall effect and coagulation of colloidal systems

CONCLUSION

Upon performing the 3^rd experiment, Classification of Matter, I conclude that Elements are the simplest form of atoms and compound is compose of two or more elements through chemical reaction. Where some compounds are Electrolyte, conduct electricity, because they are ionic which allow charges to pass through.

I also conclude that neutralization between acid and base, which can be indicated by the use of different indicators like cabbage and nitromine, reacts to form water and salt.

Tyndall Effect is the scattering of light by a colloidal dispersion. Brownian Movement is a movement which the particles changes speed and direction erratically. Which, colloidal systems can be stable or unstable depending on  the tendency of the colloidal system to remaun a true solution.

Matter occupies space and has mass and can be classified as pure substance or a mixture where colloid is a type of mixture and pure substance can either be a element of a compound. Electrolyte is a compound that when dissolved in water, it forms a solution that can conduct electricity.
