6. TestProcedureResults AppearanceExamine the liquid. Observe its color, transparency, and thicknessDescribe your observation in detail Miscible in water 1. add 100 drops of water into plastic container A 2. add one pipette dropper of liquid being tested into plastic container A 3. observe If liquid beads up forming a separate layers liquid is not miscible in water If liquids mix liquid is miscible in water Miscible in Ethanol 1. add 50 drops of ethanol into plastic container B 2. add one pipette dropper of liquid being tested into plastic container B 3. observe If liquid beads up forming a separate layers liquid is not miscible in ethanol If liquids mix liquid is miscible in ethanol Contains Water 1. add one dropper of liquid being tested into plastic container C 2. Dip ½ of pink cobalt chloride paper into plastic container C liquid, remove, and place of paper towel 3. observe If pink cobalt chloride paper turns yellowish color, liquid contains water If pink cobalt chloride paper turns a darker color, liquid does not contain water Corrosive1. Dip ½ of a pH paper strip into the liquid into plastic container C and remove and place on paper towel. 2. observe 3. match the color of the pH strip to pH color scale If the pH factor is between 3 and 11, the liquid is not corrosive.
