II. Objectives: * To learn different methods and techniques of separating components of mixtures * To appreciate the importance of such separation techniques * To apply different methods and techniques in separating components of mixtures
III. Results and Observations Separation of components with different solubilities * AMMONIUM CHLORIDE, SODIUM CHLORIDE, SAND the wt. of mixture with evaporating dish after 1st heating is?? g. And after Its 2nd heating?? g. The method used to separate that mixtures are Filtration and Evaporation. Filtration is the process of separating the solid from the liquid by using a porous filter. And Evaporation is the process of reducing the volume of a solution.
The substances that separated are the sand and the salt. What is the purpose of adding water to the residue (the solid particles that remained on the filtering medium)? We add water to the residue so that we can easily separate the sand from the salt. And after the filtration the sand was left.
Separation of solute between immiscible solvents * IODINE CRYSTALS + WATER + N-HEXANE the N-hexane turned to color violet. The method used to separate that mixture is Extraction. Extraction is the distribution of a solute in two immiscible solvents.
The substances that separated are H2O and Iodine crystals with N-hexane. The iodine crystals have a very low solubility in water and it dissolves quickly when it combines with N-hexane and when it mixed.
Separation of components with different volatilities * WATER AND ACETONE when the water H2O and acetone was heated, the acetone evaporated from the beaker and condensed to the test tube. The method used to separate the mixture is Distillation. Distillation is the process of separating liquid mixtures with components of varying degrees of volatility or significant differences in boiling point. The water and the acetone separated.
The water and Acetone has different
