The volume of water used to dissolve the sugar with the different masses, should remain the same for each trial performed.

To collect accurate data. This is because when sugar is placed in water, the sucrose molecule start breaking from the sugar crystal, and begin to immediately get surrounded by water molecules, and eventually bond with the water molecules. Therefore, the higher the volume of water, the higher the amount of water molecules there will be available for the sucrose molecules to bond with, which would result in the sugar dissolving faster.

A 100 ml beaker will be used to measure 50ml of water, which will be the amount of water used during all of the trials. (30g)

The number of time one uses the stirring rod to stir the …show more content…
Since when one stirs substances, the movement of the solvent increases. Which results in the solute molecules breaking and being exposed to it’s solvent and bonding with it’s molecules, therefore dissolving in it. Therefore, the larger the amount of time one stirs, the faster it would dissolve, since stirring has the ability to increase the speed that a substance dissolves in.

The water and sugar will be stirred twice every 10 seconds during all of the trials.
The temperature of the water used to dissolve the sugar, should remain the same for each trial performed.

Because water from different places are of different temperature, and the temperature of the water used has a great impact on the time the sugar will take to dissolve. This is because the higher the temperature of water, the faster they would melt. Therefore, if the temperatures of water aren’t the same throughout the experiment, the data collected would not be precise.

The water used will always come from the tap located in the science lab, to ensure that there is no difference in temperature, and the temperature remain the same during all of the trials.

The sugar dissolved, should be of the same type for each trial
