SEPARATION OF MIXED
SALT SOLUTION FILTRATION KITCHEN

Activity 8.1

I.       Purpose                                 : separate the salt solution

II.       Basic Theory                         :

      As described in the previous unit, the physical property is a character of substance that can be observed, measured, or tasted by our senses, such as the colour, substances size, substances form, odor, taste, boiling point, melting point, solubility, elasticity, hardness, and electric transmission power. Those characteristics can be used as the basic of the following mixture separation techniques.
