Answer:
One effective procedure for dissolving a cube of sugar in water quickly using equipment available in a standard chemistry lab is:
Boil a specific amount of water in a beaker or flask on a hot plate or Bunsen burner.
Once the water has reached boiling point, remove it from the heat source and add the sugar cube.
Stir the mixture vigorously using a stirring rod or magnetic stirrer until the sugar has completely dissolved.
If necessary, cool the solution by placing the beaker or flask in an ice bath or allowing it to cool naturally to room temperature.
This procedure is effective because the solubility of sugar in water increases with temperature. By heating the water, the energy of the water molecules is increased, which allows them to break apart the sugar molecules more easily. Stirring the mixture further increases the contact between the sugar and the water, which facilitates the dissolution process. The cooling step is necessary to prevent recrystallization of the dissolved sugar as the solution cools down, which would result in a slower dissolution process. Overall, this procedure can dissolve a sugar cube in water quickly and efficiently using equipment readily available in a standard chemistry lab.
