Experiment#4[Column Chromatography]
Aim of experiment
In column chromatography, a stationary phase, the solid absorbent, is held in a vertical column and a mobile phase, the liquid eluent, is added to the top and allowed to flow down through the column. Column chromatography is generally used as a purification technique it isolates desired compounds from a mixture.
Experiment theory reaction equation
5gal2o3+15mlEthanol
Physical constants of reactants and products

Column chromatography is generally used as a purification technique it isolates desired compounds from a mixture.
Experiment theory reaction equation
5gal2o3+15mlEthanol
Physical constants of reactants and products
10g of Alumina / 1ml of the mixture of Methylene blue(BB)
10-15ml of ethanol + more / 1ml of the mixture of methyl orange
Experimental procedures and observations
Procedures
Observations
1.Use a column with a diameter of 1.5cm and length of 15cm. Set up the column vertically with a clamp. Fill half of the column with ethanol, and push a small piece of cotton to the bottom of the column.
-` Need to adjust height well.
2. Weigh 10g of alumina into beaker, add 15ml of ethanol and moderately mix.
