Does the amout of Solution effect the Crystalization of Copper Sulfate - Research Paper Example

The experiment requires the following; Boiling tube, thermometer, Source of heat and 8.5g of CuSO4 Procedurally, transfer 8.5g of CuSO4 into a dry clean beaker. To the boiling tube, add distilled 20cm3 water and warm the mixture until all the solid has dissolved. Place the thermometer in the boiling tube and remove the flame and allow the solution to cool while stirring with the thermometer. Note the temperature at which crystals appears. Add 6cm3 distilled water into the mixture in the boiling tube and repeat the procedure.

Continue adding 6cm3 portions of distilled water until the total volume of water is 50cm3. Record the temperature at which crystals appear in each case. It’s noted that is noted that crystal appear faster, in the beaker that is highly concentrated than those that are highly diluted. A solid that dissolves in a solvent is a solute. Solvent of a given mass dissolves a fixed amount of a given solute at a particular temperature. The fixed amount of solute forms a saturated solution at that particular temperature. . When temperature increases more solute dissolves because of the increase in molecular energy of water molecules that increases the interaction of water and solute particle (Giulietti, 1996) However, the amount of solution does not either increase or decrease the rate of crystallization.

This is because volume is a constant and has no effect on the rate of crystallization. The rate of crystallization varies when the temperature and concentration of the solution are altered. When the concentration is decreased the capacity to hold on water molecules is increased because of large surface area of intermolecular spaces between water molecules. This is therefore increases the capacity of water molecules to hold the solute thereby decreasing the rate at which crystals form from a cooling solution.

However, when the solute concentration of the solution is increased, the capacity of liquid molecules to hold solutes decreases because of reduced intermolecular spaces. This therefore increases the ease with which crystals reform from the solution thereby increasing the rate of crystallization. A crystal formed consists of the various atoms or molecules arranged in a uniform repeating pattern based on its unique shape. This results in the material having a specific shape and color, and having other characteristic properties.

Crystals may be big or little, but they all have the same "shape" Water can only hold a certain amount of solute at a given temperature. When the temperature of the solution is increased, the capacity of water to hold solids substance is increased than cold water because increased energy, making room for more solid substance to dissolve. When no more of the solid substance can be dissolved, the solution termed as saturated. As the solution
