Potassium flame test is carried out by dipping a clean flame test loop in the sample solution. The suction filtration set as in Figure 1 was set. In a quantitative characterization, the chemical formula and the structure i. Edexcel Additional Science.
The solution was filtered to remove the residue and other impurities. Materials and Methods: The first part of this experiment was to dissolve the aluminum foil in 1.
Place the foil in a reaction beaker labeled with your initials. Add distilled water dropwise while stirring until the alum dissolves. The alum crystal was air dried in desiccator and the mass of the crystal is recorded after drying.
Cool the crucible to room temperature on the triangle this takes about ten minutes. The melting point is higher than the theoretical melting point because thin coating of paint outside the aluminium can is not removed.
Record your results. This cause the reflux system cannot be used to condense hydrogen gas produced from the reaction between aluminium scraps and potassium hydroxide solution hence the experiment is stopped due to sudden water-break.
When aluminum cans are recycled curbside, they help pay for community services.
