Using F-test‚ the F-computed for color and odor on researchers’ observation were 1411.27 and 117.28 respectively‚ highly significant while texture was 1.91‚ insignificant at F.05 (2‚ 26) = 3.369. On the survey‚ the F- computed for color‚ odor and texture were 270.80‚ 3.56 and 13.87 respectively‚ highly significant

6-4-2013 A pure substance or chemical substance is a material that is homogeneous. It has consistent properties throughout the sample.” Pure substances can be described by both physical and chemical properties”. Physical properties can include‚ color‚ odor‚ melting point‚ boiling point‚ and solubility in various solvents‚ etc. The observation of these physical properties does not involve any chemical change in the substance‚ it is still the same. Meaning it is still the same pure substance it was before

COMPARATIVE INVESTIGATION OF ORGANIC COMPOUNDS Abstract Organic compunds were examined to a comparative investigation to differentiate the properties of each sample. The physical state at room temperature‚ odor and color of the sample were noted by simple observation. In terms of solubility in H2O‚ 5% NaOH solution and 5% HCl solution‚ the samples were classified as to miscible‚ slightly immiscible or immiscible for liquid; and very soluble‚ soluble‚ partially soluble or insolubse for solid.
